Overview

Sodium formate ne byproduct samar a lokacin da samar da pentaerythritol. Wannan abu ne ya fi amfani a matsayin rage wakili a cikin kwayoyin kira halayen. Shiri na sodium formate ake dangantawa da wasu matsaloli a cikin tsarkakewa wannan fili. Saboda haka, a karshen samfurin ne ko da yaushe wani kadan admixture na pentaerythritol Irinta. Sodium formate - shi ne mai crystalline foda, fari ko dan kadan grayish launi. Wani lokaci da sayarwa gana sodium formate da kadan greenish tint. Impurities ba a shi ne ba a bayyane zuwa ga tsirara ido. A foda, wanda aka kasuwanci, da taro sulusi da murabba'i na asali abu ya kamata ba kasa da kashi 92%. Qualitatively, sodium formate takamaiman nauyi na ruwa kada wuce 3%. A cewa sinadarai da kuma sweeteners. A cikin sharuddan su glucose ciki ba zai iya wuce 1%.

Don kwanan wata, akwai ba guda masana'antu samar da wannan sinadaran. Tun sodium formate aka samar a matsayin ta-samfurin, shi na bukatar ƙarin musamman aiki da fasaha. Wasu kamfanonin kokarin haduwa da wannan abu, amma irin wannan samarwa ne tsada sosai, kuma shi bai dace da taro samar.

Da dabara na sodium formate - HCOONa. Tun da yake wannan abu ya ƙunshi formic acid wanda yake da kyau kwarai protivolednym reagent shi ne mafi akai-akai amfani da maganin daskarewa.
