Dicumyl Peroxide used as curing Agent for different Types of Rubber Matrices Part I: Effect of Temperature

Several elastomers were cured with dicumyl peroxide at different vulcanization temperatures. The focus of the work was the investigation of the influence of curing temperature on curing characteristics of rubber compounds. Subsequently, crosslink density and physical mechanical properties of vulcanizates were evaluated. The results demonstrated that higher curing temperatures lead to a total acceleration of cross-linking process. The effect of temperature on the crosslink density was low and was dependent on the structure of tested rubbers. Physicalmechanical properties of vulcanizates were almost not influenced by curing temperature.

Photocatalytic Conversion of Benzyl Alcohols/Methyl Arenes to Aryl Nitriles via H-Abstraction by Azide Radical

This report presents the visible-light-assisted synthesis of aryl nitriles from easily accessible alcohols or methyl arenes in the presence of O-2. Organic photoredox catalyst, 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene), induces single electron transfer (SET) from azide N(3)(-)and generates azide radical N-3(.).The photogenerated N(3)(.)abstracts H atom from alpha-C-H bond of benzylic system, which provides aldehyde and hydrazoic acid (HN3) in situ. This reaction subsequently forms azido alcohol intermediate that transforms into nitrile with the assistance of triflic acid (Bronsted acid). A range of alcohols and methyl arenes successfully underwent cyanation at room temperature with good to excellent yields and showed good functional group tolerance.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 766-84-7. COA of Formula: C7H4ClN.

Method for the Preparation of N-protected beta-Cyano L-alanine Tertiary Butyl Esters

Here we report a simple, efficient and scalable one-pot procedure for the synthesis of N-protected beta-cyano L-alanine tertiary butyl esters from N-protected L-asparagines. Reaction of N-protected L-asparagines with 2.2 equivalents of (Boc)(2)O and catalytic amount of N,N-dimethylamino pyridine (DMAP) in tertiary butanol at room temperature resulted N-protected beta-cyano L-alanine tertiary butyl esters. We also synthesized N-protected beta-cyano L-alanines from the obtained crude N-protected beta-cyano L-alanine tertiary butyl esters without column chromatography on gram scale in good yields. Control experiments gave the corresponding nitrile acids over the tertiary butyl esters. Later, we synthesized nitrile containing dipeptides by coupling N-Boc-beta-cyano L-alanine 4 a with amino acid methyl ester hydrochlorides.

Clarification of the USP compendial procedure for phenoxybenzamine hydrochloride via updating impurity profiles

The current United States Pharmacopeia-National Formulary (USP-NF) and the British Pharmacopoeia phenoxybenzamine (PBA) hydrochloride drug substance and drug product monographs describe an HPLC procedure for the determination of a specified impurity tertiary amine phenoxybenzamine and use the resolution of an unknown related substance from PBA as a system suitability criterion; however, neither structural information of the unknown related substance is provided nor reference standards of the two impurities are available. The ambiguity in pharmacopeias poses difficulties in implementing the procedure for quality control. To clarify the degradation pathways, and incorporate the impurity profile of PBA into the USP monographs, the degradation of PBA was revisited. PBA undergoes rapid degradation in neutral or basic aqueous solutions to generate the tertiary amine phenoxybenzamine as the predominant degradation product, which was confirmed as phenoxybenzamine hydroxide (PBA-OH). In addition, the unknown related substance was proposed as the phenoxybenzamine nitrile (PBA-CN) on the basis of LC-MS studies. The identity of PBA-CN was unambiguously verified via chemical synthesis, HPLC and NMR analyses. A stability-indicating method was developed and validated for the determination of PBA and its impurities, and was used to support USP monograph modernization. (C) 2020 Elsevier B.V.

Construction of dual coordination networks in epoxidized butadiene-acrylonitrile rubber/CuSO4 composites and mechanical behaviors

Dual coordinated cross link networks were designed in epoxidized butadiene-acrylonitrile rubber (NBR)/CuSO4 composites to make commercial NBR become advanced soft materials. First, NBR was modified through organic peroxy acid method to produce epoxidized butadiene-acrylonitrile rubber (ENBR). Next, CuSO4 was introduced in bulk to form strong Cu2+-nitrile coordination bonds acting as strong cross link points and Cu2+-epoxy bonds acting as weak cross link points. XPS analysis, FT-IR spectra and rheological curves proved the dual coordination bonds. Curing rheology curves, crosslinking density and thermal properties effectively demonstrated the formation of related dual cross link networks. The ENBR/CuSO4 composites exhibited excellent mechanical properties due to the synergistic effect of strong and weak metal-ligand coordination networks. During stretching, the weak coordination bonds acted as sacrificial bonds which could dissipate energy, while the strong coordination bonds sustained the network and imparted the elasticity. Under the combined functions of dual coordination bonds, the modulus, tensile strength, and toughness of ENBR/CuSO4 composites could be improved and tuned by controlling the structure parameter of coordination networks such as epoxidation degree and content of CuSO4.

Improving dielectric properties of poly(arylene ether nitrile) composites by employing core-shell structured BaTiO3@polydopamine and MoS2@polydopamine interlinked with poly(ethylene imine) for high-temperature applications

For organic film capacitors, the dielectric materials with high-k, flexible and high heat-resistance are desired. Herein, a kind of hybrid particles were fabricated via self-polymerization and crosslinking reaction, containing core-shell structured BaTiO3@polydopamine (BT@PDA) and MoS2@polydopamine (MoS2@PDA) interlinked with poly(ethylene imine) (PEI) to perserve better interfacial interaction and uniform dispersion in poly(arylene ether nitrile) (PEN) composites. The results suggest that the designed PEN-based composites demonstrate remarkable dielectric responses. The incorporation of hybrid particles endows the polymer composites with high relative dielectric constant and comparable low dielectric loss due to the construction of diffuse electrical double layer and more micro-capacitor networks in PEN-based composites. Particularly, the dielectric constant of composite loaded with 15 wt% hybrid particles is about 254% higher than that of PEN matrix at 1 kHz, while maintaining a relatively low dielectric loss (< 0.03). More importantly, the PEN-based composites maintain their dielectric constants from room temperature to 160 degrees C, thus exhibiting outstanding permittivity-temperature stability, which can better meet the requirements of high temperature applications. In conclusion, this is a feasible way to incorporate hybrid particles containing core-shell structured BT@PDA and MoS2@PDA into polymer matrix to design dielectric composites with excellent permittivity-temperature stability.

In Situ Construction of Uniform and Robust Cathode-Electrolyte Interphase for Li-Rich Layered Oxides

High-energy-density Li-rich layered oxides (LLOs) as promising cathodes for Li-ion batteries suffer from the dissolution of transition metals (especially manganese) and severe side reactions in conventional electrolytes, which greatly deteriorate their electrochemical performance. Herein, an in situ anchoring + pouring synergistic cathode-electrolyte interphase (CEI) construction is realized by using 1,3,6-hexanetricarbonitrile (HTCN) and tris(trimethylsilyl) phosphate (TMSP) electrolyte additives to alleviate the challenges of an LLO (Li1.13Mn0.517Ni0.256Co0.097O2). HTCN with three nitrile groups can tightly anchor transition metals by coordinative interaction to form the CEI framework, and TMSP will electrochemically decompose to reshape the CEI layer. The uniform and robust in situ constructed CEI layer can suppress the transition metal dissolution, shield the cathode against diverse side reactions, and significantly improve the overall electrochemical performance of the cathod with a discharge voltage decay of only 0.5 mV cycle(-1). Further investigations based on a series of experimental techniques and theoretical calculations have revealed the composition of in situ constructed CEI layers and their distribution, including the enhanced HTCN anchoring effect after lattice densification of LLOs. This study provides insights into the in situ CEI construction for enhancing the performance of high-energy and high-voltage cathode materials through effective, convenient, and economical electrolyte approaches.
