Khoom Sodium Formate

SODIUM FORMATE

Sodium formate yog dawb absorbent hmoov los yog siv lead ua nrog me ntsis formic acid tsw. Soluble hauv dej thiab glycerol, me ntsis soluble hauv ethanol, insoluble hauv ether; Tshuaj lom.

Nyob rau hauv ib txwm muaj xwm txheej, sodium formate cia kev ruaj ntseg, noo noo nqus, yooj yim delixing, cia thiab thauj cov txheej txheem yuav tsum xyuam xim rau cov dej noo, tsis hloov qhov xwm ntawm cov khoom thaum lub noo noo nqus caking, yuav siv tau ib txwm tom qab crushing.

Nyob rau hauv chav tsev kub, nws yog ib tug dawb los yog lub teeb daj crystalline khoom nrog me ntsis delixing. Me ntsis formic acid tsw. Nws yog hygroscopic. Thaum kub kub, nws decomposes rau hauv sodium oxalate thiab hydrogen, thiab ces sodium carbonate. Dissolves nyob rau hauv li 1.3 qhov chaw dej. Soluble nyob rau hauv glycerol, me ntsis soluble nyob rau hauv ethanol, octanol, insoluble nyob rau hauv ether. Nws cov tshuaj aqueous yog alkaline. Tus txheeb ze ntom ntom yog 1.92. Melting point 253 degree. Nws yog stimulating. Cov khoom feem ntau muaj 2 molecules ntawm cov dej siv lead ua.

Nws yog siv los ua camouflage acid nyob rau hauv kev lag luam tawv, chromium tannery, raws li ib tug catalyst thiab stabilizing hluavtaws tus neeg sawv cev, raws li ib tug txo tus neeg sawv cev nyob rau hauv lub luam ntawv thiab dyeing kev lag luam, rau zus tau tej cov tshuaj pov hwm hmoov, oxalic acid thiab formic acid. Precipitate precious hlau. Complex ions ntawm trivalent hlau tuaj yeem tsim hauv kev daws teeb meem. Nws muaj cov nyhuv buffering thiab tuaj yeem kho tus nqi pH ntawm cov kua qaub muaj zog.

Siv nyob rau hauv alkyd resin coatings, plasticizers, siab explosives, acid resistant cov ntaub ntawv, aviation lubricating roj, nplaum additives.
