Abstract: The problem to be solved by the present invention is to easily and efficiently produce an amino acid having 2 to 7 carbon atoms as a high-purity solid without complicated operation, which is useful as a synthetic intermediate for medicines or agrochemicals. The present invention is characterized in comprising a step of precipitating solid amino acid with high purity. In the present invention, the by-produced salt composed of the sulfonic acid and the amine was removed to the mother liquor by reacting an amine with a sulfonic acid salt of amino acid in an aprotic polar solvent, or by reacting a sulfonic acid with an amine salt of amino acid in an aprotic polar solvent. The sulfonic acid salt of amino acid, for example, may be produced by reacting a N-(tert-butoxycarbonyl) amino acid with a sulfonic acid, or by reacting an amino acid tert-butyl ester with a sulfonic acid.

Abstract: Improved processes for making an N-acyl amino acid salt from a fatty alkyl ester or a polyol ester are disclosed. Each process uses a polyol selected from glycerin or propylene glycol in an amount effective to keep the reaction mixture fluid until conversion to the N-acyl amino acid salt reaches the desired level of completion. In one process, a fatty alkyl ester reacts with an amino acid salt in the presence of glycerin or propylene glycol to produce an N-acyl amino acid salt. In another process, a polyol ester reacts with the amino acid salt in the presence of added glycerin or propylene glycol to produce the N-acyl amino acid salt. We surprisingly found that an effective amount of glycerin or propylene glycol minimizes or eliminates reaction mixture solidification or foaming, reduces color, and minimizes the level of di- and tripeptide by-products. In a related process, water is added when conversion of the amino acid salt to the N-acyl amino acid salt is in the range of 50 to 90 mole %.
Abstract: N-alkyl, N-alkenyl, N-cycloalkyl, N-aryl amino or imino propionic acids with an alkyl chain ranging from 6 to 18 carbons, or alkenyl chain from 8 to 30 carbons, are obtained from a reaction process in the absence of solvent at a temperature range from 30 to 180° C. and a time of 1 to 10 hours at atmospheric pressure. Formulations composed of N-alkyl or N-alkenyl or N-cycloalkyl or N-aryl amino or imino propionic acids, polyethers derived from propylene oxide or ethylene oxide or copolymer thereof and a solvent consisting of aromatic compounds such as toluene or xylene, diesel or gasoline or alcohols such as isopropanol and ethanol, or mixtures thereof, are obtained inhibit ferrous metal corrosion of pipelines and storage tanks and transport crude oil and liquid fuels.
