发明名称 REFINING METHOD OF N-CYCLOHEXYLBENZOTHAIZOLYL-2-SUcrystallised. LFENAMIDE
摘要 <p>A refining method of N-cyclohexylbenzothaizolyl-2- -sulfenamide wherein said compound is separated from product's solid admixtures having a particle size up to 30 mm and can be characterised in that N-cyclohexylbenzothaizolyl-2-sulfenamide is being mixed with a concentrated cyclohexylamine or, optionally, with at least 20 percent aqueous solution thereof, in a ratio of 2 - 50 moles of cyclohexylamine per 1 mole of N-cyclohexylbenzothaizolyl-2-sulfenamide, at 15 - 70 degrees Celsius, preferably 45 - 60 degrees Celsius. A homogenous solution thereby obtained is adulterated at 5 - 50 percent by weight of cyclohexylamine and is cooled down at 0 - 30 degrees Celsius after which N-cyclohexylbenzothaizolyl-2-sulfenamide is</p>
