설명

일반 설명

Crystals of sodium chloride belong to the cubic crystal system. It is widely employed preservative for meat, vegetable and fish products. Its effect on the growth of salmonellae (mixed inoculum of Salmonella thompson, S. stanley and S. infantis) has been investigated in laboratory medium.

애플리케이션

Sodium chloride was used in the dissolution of polymers such as poly(allylamine hydrochloride), sodium poly(styrenesulfonate) and poly(acrylic acid).
