Isocyanate, a pivotal chemical intermediate to synthesize polyurethane with widespread applications in household appliances, automobiles, and construction, is predominantly produced via the phosgene process, which currently holds paramount status industrial isocyanate production. Nonetheless, concerns arise from toxicity of corrosiveness hydrogen chloride, posing safety hazards. The synthesis using nonphosgene methods represents promising avenue for future development. This article primarily...
The methoxycarbonylation of aniline (AN) with dimethyl carbonate (DMC) to produce methyl N-phenylcarbamate (MPC), a key intermediate in non-phosgene diphenylmethane diisocyanate (MDI) synthesis, is facilitated using newly developed CuO-CeO 2 ...
A new route for synthesizing diisocyanates containing a furan ring structure from renewable biomass is proposed. The yield of each step high, and the reaction conditions are mild easy to operate, offering prospects industrialization.
In this study, metallic vanadium was used as catalysts for direct amination of toluene with hydroxylamine to produce toluidine under mild conditions. High conversion and selectivity were obtained, corresponding 87.62% 96.45% respectively. Additionally, thermodynamic kinetic calculations carried out. It concluded that the reaction dominated by kinetics, distribution three products being para > ortho meta. The computational experimental results indicated process involves an amino radical mechanism.
A new method for synthesizing 2-aminomethylpiperidine by selective hydrogenolysis of bio-renewable 2,5-bis(aminomethyl)furan was developed. The yield can reach 72% under mild conditions at 140 °C and 1 MPa H 2 pressure.
<p indent=0mm>Adiponitrile is a key presursor to synthesize hexamethylenediamine that specifically used for the production of nylon 66 and hexamethylene diisocyanate (HDI). Both HDI are dispensible chemical industries: Nylon widely fibers engineering plastics, towards clothing, electrical appliances, automobiles, military industry; while important synthesis high-grade polyurethane automotive coatings industries. In addition, also as curing agent rocket propellant, highlighting significance...
Glycerol dimethyl ether (2,3-dimethoxy-1-propanol) is one kind of potential fuel additive that can be synthesized from methanol and epichlorohydrin with high selectivity. The isobaric vapor–liquid equilibrium data (VLE) for two binary systems, (1) + (2) glycerol (3) were measured in a modified Ellis recirculation still at 101.3 kPa. VLE correlated using the nonrandom two-liquid (NRTL) universal quasichemical activity coefficient (UNIQUAC) models, calculated compositions temperature by NRTL...
Abstract BACKGROUND Hydroxylamine (NH 2 OH) is an important chemical raw material, which widely used in large‐scale synthesis of cyclohexanone oxime (COX) for nylon 6 manufacture. At present, inorganic acids are usually employed to stabilize NH OH form solid hydroxylamine salts. However, most these salts suffer from the problems serious equipment corrosion, environmental pollution and difficult recovery acids. To address issues, herein, a novel betaine hydrochloride (BHA) was formulated...
Dimethyl carbonate is an important green chemical that has been widely used in the industry. In production of dimethyl carbonate, methanol oxidative carbonylation studied, but conversion ratio using this method too low, and subsequent separation requires a large amount energy due to being azeotrope. paper, strategy "reaction instead separation" proposed. Based on strategy, novel process developed combine DMC with dimethoxymethane (DMM) ether (DME). The co-production was simulated Aspen Plus...
In this study, vanadium monomers were used as catalysts for direct amination of toluene with hydroxylamine to produce toluidine under mild conditions, resulting in a high yield (84.51%) the optimal reaction conditions. Thermodynamic and kinetic calculations performed using Gaussian 09 software. It was concluded that dominated by kinetics, distribution three products being para > ortho meta. Moreover, an amino radical mechanism proposed based on calculation results.
The synthesis of polyurethane from renewable biomass is crucial for pursuing a sustainable future and bio-based economy. traditional production process hexamethylene-1,6-diisocyanate (HDI) involves highly toxic phosgene, environmental...
