Reaction product of amine, alcohol and acylating agentdoi:US6407170 B1A dispersant is prepared from an amine and a hydrocarbyl-substituted acylating agent, wherein the hydrocarbyl substituent is a polymerized olefin having a polydispersity {overscore (M)} w /{overscore (M)} n of greater ...
The reactivity of half esters toward the reaction with primary amine has been compared with the reactivity of ordinary esters. The reaction was enhanced by introducing hydroxyl groups into the alcohol moiety of esters, and it took place in solutions under mild conditions. The reactivity enhancement ...
A Re-Examination of the Polyurethane Reaction initial reaction with alcohol to form tin alkoxides, while the other mechanism involves the reaction of a metal-isocyanate complex with uncomplexed alcohol... E Sacher - 《Journal of Macromolecular Science Part B》 被引量: 16发表: 1979年 Physicochemi...
A convenient and efficient one pot sequence has been developed for transformation of alcohols to amine using sodium oxide and p-Tolune sulphonyl chloride with zinc and zinc chloride at mild conditions. KeyWords: One pot, Amine, Alcohol, zinc chloride, Zinc,paratoulene sulphonyl chloride. DOI: ...
Some method about synthesis of piperazine with aliphaticaminewere introduced. 介绍了由脂肪胺合成哌嗪的几种方法. 互联网 Inhibitor HZ 1 was synthesized by the reaction ofamineand alkylogen. 通过采用胺类和卤代烷反应,合成出在盐水及泥浆介质中具有较好缓蚀效果的缓蚀剂HZ-1. ...
The reaction of multi-aliphatic primary amine with epoxy resins does not need catalyst, but different additives have different effects on the reaction. A series of proton donor materials accelerate the curing reaction, for example, alcohol, phenol, carboxylic acid, sulfonic acid and water all have...
1. Appearance: Usually white or light yellow solid. 2. Solubility: easily soluble in water and alcohol solvents. 3. Stability: Relatively stable at room temperature. Purpose: 5, 6-diethyl-2, 3-dihydro-1h-indene-2-amine hydrochloride is often used as a drug intermediate and can be used to...
A matching dehydrogenase and transaminase pair was engineered with regard to substrate recognition, catalytic activity, and cofactor specificity with the final goal to convert the bicyclic dialcohol isosorbide into a diamine by a multistep biocatalytic process. Individual catalytic turnover rates as well...
In the transalkylation of tertiary amines, unexpected higher yields are achieved requiring substantially less catalyst and much shorter reaction times at lower reaction temperatures using a homogeneous catalyst in the presence of an alcohol solvent and carbon monoxide. The process may be exemplified by ...
Reaction of 18 μM LSAO active sites, under anaerobic conditions, with 2 mM Br-ethylamine in potassium phosphate buffer, pH 7.0. Different spectra are recorded in a Thunberg-type spectrophotometer cuvette immediately after addition of Br-ethylamine from 4 min to 20 min with interval...
