Abstract
A process for the direct neutralization of N-acyl sarcosines wherein all raw materials and products are in the liquid state up to the final crystallization of the product. The N-acyl sarcosines are neutralized in a continuous or batch mode with caustic such as aqueous hydroxide at elevated temperatures to produce a molten, free flowing liquid, which can then be crystallized to solid product.
Claims10
A process for the neutralization of N-acyl sarcosine, consisting essentially of reacting said sarcosine with caustic at a temperature higher than the melting point of said sarcosine, and crystallizing the resulting neutralized product.
A process for the neutralization of N-acyl sarcosine, consisting essentially of reacting said sarcosine with caustic at a temperature of about 70.degree.-100.degree. C. and at a reduced pressure of at least 20 inches Hg.
