The instant invention is directed to a process for producing organic phosphinites by a process wherein a disubstituted halophosphine is reacted with a primary, secondary, or tertiary alcohol or phenol in the presence of a tertiary amine base wherein the reaction is conducted at a temperature ...
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 was related with the number of hydroxyl groups in the half esters; the half ester derived from glycerol reacted easily with ...
Because they are very susceptible to deterioration during storage, we do not sell any isocyanates (R–NCO). Some acyl azides (Reagents for Modifying Alcohols—Section 3.2), however, are readily converted to isocyanates (Figure 1.1.2), which then react...
被引量: 8 摘要: Mixtures of alcohols and water-soluble amines are reacted with alkylating agents to produce novel surfactants. Water-soluble amines are normally not surfactant materials when alkoxylated, but when alkoxylated together with alcohols form a highly effective surfactant product.收藏...
after conversion to an acid chloride reacted with an amine in the presence of a tertiary amine to form an amide, or the acid can be reacted with carbonyldiimidazole in the presence of a solvent and excess amine to form an amide... B Shroot,C Hensby,J Maignan,... 被引量: 0发表: ...
Primary amines react with a carbonyl compound to yield imines, whereas secondary amines react to yield enamines. Trifluoroacetylacetone and cyclohexanone have been used to analyze a series of long chain and alicyclic monoamines, aliphatic diamines and aromatic amines. Furfural, benzaldehyde, 2-thiop...
The change in the color of the solution, before and after bubbling CO2, also indicates that the amine surfactants react with CO2 in water and generate a new structure. The new structure makes the amine compound have well solubility and surface active. In these three compounds, the foaming ...

Polyvinylaminals, optionally as the formed copolymer with polyvinylhemiaminals, and polyvinylacetals are useful as flocculants and epoxy resin and polyurethane crosslinking agents and are provided by reacting a poly(vinylamine) or a copolymer containing vinyl alcohol and vinylamine units with a ...
A primary aliphatic amine is defined as an organic compound that reacts with nitrous acid to liberate nitrogen and form an alcohol. It is an important analytical tool in studying proteins and amino acids due to its ability to determine free primary amino groups. ...
