설명

애플리케이션

Sodium sulfate can be used as a dehydrating agent for the synthesis of 1,3-diaryl-2-propen-1-one oxime via the condensation of 1,3-diaryl-2-propen-1-one with hydroxylamine hydrochloride. It can also be used as a drying agent in organic synthesis for the removal of traces of water from organic extracts. It is used for drying almost all compounds including fatty acids, aldehydes, ketones, and alkyl and aryl halogenides.

특징 및 장점
