Chaw tsim tshuaj paus kom zoo formic acid 85% CAS: 64-18-6

Chaw tsim tshuaj paus zoo nqe formic acid 85% CAS: 64-18-6 Featured Duab

Cov lus piav qhia luv luv:

Formic acid yog qhov tseeb, tsis muaj kob nrog kua pungent tsw. Formic acid tau tshwm sim thawj zaug los ntawm qee cov ntsaum thiab tau muaj npe tom qab Latin formica, lub ntsiab lus ntsaum. Nws yog tsim los ntawm kev txiav txim ntawm cov sulfuric acid on sodium tsim, uas yog tsim los ntawm carbon monoxide thiab sodium hydroxide. Nws kuj yog tsim tawm raws li cov khoom lag luam hauv kev tsim cov tshuaj xws li acetic acid.
Nws tuaj yeem xav tau uas siv cov formic acid yuav txuas ntxiv ua kom nws hloov cov acorganic acids thiab muaj lub luag haujlwm hauv lub zog thev naus laus zis tshiab. Formic acid toxicity yog ntawm kev txaus siab tshwj xeeb raws li cov kua qaub yog cov metabol ntawm metylolite ntawm methanol.

Cov Khoom: Ua cov kua qaub yog cov kua tsis muaj kob uas muaj pungent tsw. Nws yog qhov ruaj khov khov, sib txuas ua ke, thiab hygroscopic tshuaj lom neeg cov tshuaj. Nws tsis sib xws nrog H2SO4, muaj zog caustics, hurfuryl cawv, hydrogen peroxide, muaj lub hauv paus muaj zog thiab reacts nrog cov neeg sawv cev oxidising.
Vim yog cov pab pawg -co, formic acid consarts qee tus cwj pwm ntawm aldehyde. Nws tuaj yeem tsim ntsev thiab ester; Muaj peev xwm hnov mob nrog amine los tsim cov lus cia thiab los ua cov tshuaj ester los ntawm kev sib ntxiv nrog cov tshuaj tiv thaiv hydrocarbon ntxiv ntxiv. Nws tuaj yeem txo cov nyiaj ammonia daws los tsim cov tsom iav dawb, thiab ua kom cov poov tshuaj permanganate daws teeb meem ntawm cov qauv acid.
Raws li carboxylic acid, formic acid, feem ntau ntawm cov tshuaj tib yam hauv reaceris los tsim dej soluble. Tab sis formic acid tsis yog ib qho carboxylic acid raws li nws tuaj yeem hnov mob nrog alkenes los tsim cov ntawv estre.

Cov ntawv thov ntawm formic acid 85%

1.Cormic acid muaj ntau cov kev siv lag luam. Nws yog siv rau hauv kev lag luam tawv rau degreeand tshem cov plaub hau los ntawm kev zais thiab raws li ib qho kev xyaw ua ke hauv kev tooning formulations. Nws yog siv los ua alateex coagulant nyob rau hauv ntuj roj hmab ntau lawm. Ua cov qauv acid thiab nws cov qauv tsim yog siv aspreservates ntawm silage. Nws yog qhov tshwj xeeb tshaj yog muaj nuj nqis hauv Tebchaws Europe uas yuav tsum tau siv cov kev cai lij choj nategantibterial es tsis yog cov tshuaj tua kab mob hluavtaws. Silage yog fermented nyom thiab cov qoob loo uas khaws cia hauv silos thiab siv rau lub caij ntuj no pub. Silage yog tsim tawm thaum Anaerobic fermentationwhen cov kab mob tsim cov kua qaub uas txo qis ph, tiv thaiv kab mob. Acetic Acidand Lactic acid yog qhov xav tau acids thaum lub sijhawm ua si fermentation. Formic acid yog siv nyob rau hauv silageprocessing los txo cov kab mob uas tsis ntxim nyiam thiab cov pwm loj hlob. Formic acid txo cov neeg sau ntawv tawm tsam uas yuav tsim butyric acid ua rau lwj. Ntxiv rau kev tiv thaiv sicespecage, acid acid pab txuag cov protein protein, txhim kho cov ntsiab lus, thiab cov ntsiab lus archervessugar. Formic acid yog siv los ua miticide los ntawm beekeepers.

2.formic acid yog cov tsw qab uas yog kua thiab tsis muaj kob, thiab muaj tus ntxhiab pungent. Nws yog mistible hauv dej, cawv, ether, thiab glycerin, thiab yog tau los ntawm kev tshuaj lom neeg lossis oxidation ntawm methanol lossis formaldehyde.

3.Cormic kua qaub tshwm nyob hauv cov stings ntawm ntsaum Andebees. Nws yog siv nyob rau hauv kev tsim cov ntsev esyand, dyeing thiab ua tiav ntawm textiles thiab ua tiav ntawm cov tawv ntoo, thiab coagulating roj hmab kua txiv ntoo, thiab kuj yog areducing tus neeg sawv cev.
