Abstract

PURPOSE: To purify the titled compound, by dissolving raw mercaptothiazolines containing organic by-products such as 2-oxazolidones, 2-thiazolidones, etc. as impurities in a solvent of water at ≤ a specific temperature.
CONSTITUTION: In purifying raw 2-mercaptothiazolines containing 2-oxazolidones, 2-thiazolidones, 2-thiooxazolidones, 2-mercaptooxazolines, 2-( 2'-mercaptoethylamino)-2-thiazolins, aminoalkylthiols, etc. as impurities by subjecting them to dissolution treatment with a solvent of water, the dissolution treatment is carried out in a temperature range not to melt the by-products, preferably at ≤70°C, more preferably at ≤65°C, so the by-products are neither liquefied nor made into an oily state and 2-mercaptothiazolines are dissolved and transferred into the solvent of water. The aqueous solution phase is separated from the solid phase of by-products, and 2-mercaptothiazolines are crystallized from the aqueous solution phase.
