Synthesis and Properties of Esters of Amino Acids' Composite and Palmityl Alcohol

Abstract:

Concentrates of composite of amino acids based on hydrolysis of rapeseed meal were used to prepare esters of amino acids composite and palmityl alcohol. Effects of the ratio of raw materials, reaction time, water carrying agent and catalyst on synthesis of products were investigated. Surface-activity of these products have been also characterized. The optimums of reaction conditions were obtained. The results showed that molar ratio of palmityl alcohol and amino acids composite was 1:2, and toluene was as water carrying agent, and reaction temperature was 110°C-125°C, and the reaction time was 4 h, and mass dosage of high concentrated H₂SO₄ as catalyst was 12% of amino acids composite, and a small amount of polyethylene glycol (PEG600) was as phase transfer catalyst. The prepared product has a good foam stability.
