摘要:通过分析硼酸(ba)添加到hca水溶液中后旋光度的变化来考察硼酸(ba)与各种α-羟基羧酸(hca)的络合,并通过催化酯化反应来考察络合物的催化性能. Hca 的成员. Hca的旋光度绝对值随着ba与hca摩尔比的增加而增加,旋光度的变化率随着ba与hca摩尔比的增加而逐渐减小,在摩尔比达到最小值时比例约为三.作为催化剂,Ba除了催化hcas的酯化反应外,还可以催化羟基的乙酰化反应.与传统的atbc和atoc合成路线相比,以ba为催化剂的合成路线可以降低催化剂分离和更换的频率,同时提供浅色产品. Ba可以催化反应生成柠檬酸三乙酯,柠檬酸三乙酯的收率达到93.8%. Ba还可催化苹果酸与蒎烯反应反应生成苹果酸冰片.苹果酸冰片皂化后得冰片,收率39%.

权利人:VERSALIS SPA
摘要:The present invention relates to a polymerization process for the synthesis of vinyl aromatic polymers, in which the sequence of monomers in the chain and the linear, branched soluble, or crosslinked insoluble structure, with reactive or different polarity functions, are controlled. Said process comprises the step of polymerizing vinyl aromatic monomers by means of an Atom Transfer Radical Polymerization (ATRP) reaction with an Activator ReGenerated by Electron Transfer (ARGET), the reaction being carried out at a temperature comprised between 25° C. and 110° C. in an inert gas atmosphere in the presence of a complex catalyst containing a cupric halide and a multidentate amine ligand, feeding to the reaction an organic initiator having two geminal halogens, an alkali metal (bi)carbonate, a solvent pair of an aliphatic alcohol and an acetic ester of the same aliphatic alcohol and possibly ascorbic acid, provided that no initiator is used with three or more active halogens, or polyvinyl monomers or inimers.

摘要:The present invention is based on the synthesis of triisoamyl citrate (triisopentanol citrate) and its applications as a plasticizer for polyvinyl chloride polymers, natural and synthetic rubbers, industrial solvents, replacing petrochemical-based products such as Phthalates (Dioctyl Phthalate, Diisononyl Phthalate, Dibutyl Phthalate), Acetylated tributylcitrate, epoxidized fatty esters, isoparaffins. It is a 100% renewable, high-performance, non-toxic, biodegradable product with an extremely competitive cost. With the increase in corn alcohol production in Brazil, this technology and product adds value to the fusel oil co-product generated in corn alcohol plants.

摘要:There is disclosed a composition comprising a water-insoluble thermoplastic compound capable of stimulating collagen synthesis (CSSC), the CSSC having a molecular weight of more than 0.6 kDa and being dispersed in a polar carrier as nano-elements having an average diameter of 200 nm or less and a viscosity of 107 mPa·s or less. The nano-elements of CSSC can be capable of stimulating the synthesis of skin proteins and/or enabling the delivery of active agents upon their application to a surface to be treated therewith. Methods for preparing the compositions and uses thereof are also provided.
