Chaw Tsim Khoom Zoo Tus Nqi FORMIC ACID 85% CAS: 64-18-6

piav qhia luv luv:

Formic acid yog ib yam kua ntshiab, tsis muaj xim thiab muaj ntxhiab tsw qab. Formic acid thawj zaug tau rho tawm ntawm qee cov ntsaum thiab tau muab lub npe los ntawm Latin formica, txhais tau tias ntsaum. Nws yog tsim los ntawm kev ua ntawm sulfuric acid rau ntawm sodium formate, uas yog tsim los ntawm carbon monoxide thiab sodium hydroxide. Nws kuj tseem tsim tawm ua cov khoom lag luam hauv kev tsim cov tshuaj lom neeg xws li acetic acid.
Nws tuaj yeem kwv yees tau tias kev siv cov kua qaub formic yuav nce ntxiv tas li thaum nws hloov cov kua qaub inorganic thiab muaj lub luag haujlwm hauv kev siv tshuab hluav taws xob tshiab. Kev lom ntawm cov kua qaub formic yog qhov txaus siab tshwj xeeb vim tias cov kua qaub yog cov tshuaj lom metabolite ntawm methanol.

Cov Khoom: FORMIC ACID yog cov kua tsis muaj xim nrog lub ntxhiab tsw qab. Nws yog ib qho tshuaj lom neeg ruaj khov, yooj yim hlawv, thiab hygroscopic. Nws tsis sib haum nrog H2SO4, cov caustics muaj zog, furfuryl cawv, hydrogen peroxide, cov tshuaj oxidizers muaj zog, thiab cov hauv paus thiab reacts nrog kev tawg loj thaum kov cov neeg sawv cev oxidizing.
Vim yog pawg −CHO, Formic acid muab qee yam ntawm tus cwj pwm ntawm aldehyde. Nws tuaj yeem tsim ntsev thiab ester; tuaj yeem ua rau muaj kev cuam tshuam nrog amine los ua amide thiab los tsim ester los ntawm kev ntxiv kev cuam tshuam nrog unsaturated hydrocarbon ntxiv. Nws tuaj yeem txo cov tshuaj ammonia nyiaj kom tsim tau daim iav nyiaj, thiab ua rau cov tshuaj potassium permanganate ploj mus, uas tuaj yeem siv rau kev txheeb xyuas cov tshuaj formic acid zoo.
Ua ib qho carboxylic acid, formic acid feem ntau muaj cov khoom siv tshuaj lom neeg zoo ib yam hauv kev cuam tshuam nrog alkalis los tsim cov dej soluble formate. Tab sis formic acid tsis yog ib qho carboxylic acid ib txwm muaj vim nws tuaj yeem cuam tshuam nrog alkenes los tsim cov formate esters.

Cov ntawv thov ntawm FORMIC ACID 85%

1. Formic acid muaj ntau yam kev siv ua lag luam. Nws siv rau hauv kev lag luam tawv kom tshem cov roj thiab tshem cov plaub hau ntawm daim tawv thiab ua ib yam khoom xyaw hauv cov tshuaj pleev tawv. Nws siv ua alatex coagulant hauv kev tsim roj hmab ntuj. Formic acid thiab nws cov tshuaj pleev tawv yog siv ua cov tshuaj khaws cia ntawm silage. Nws muaj nqis tshwj xeeb hauv Tebchaws Europe qhov twg cov kev cai lij choj yuav tsum tau siv cov tshuaj tua kab mob ntuj es tsis yog cov tshuaj tua kab mob tsim. Silage yog cov nyom fermented thiab cov qoob loo uas khaws cia rau hauv silos thiab siv rau kev pub rau lub caij ntuj no. Silage yog tsim tawm thaum lub sijhawm anaerobic fermentation thaum cov kab mob tsim cov kua qaub uas txo qis pH, tiv thaiv kev ua haujlwm ntawm cov kab mob ntxiv. Acetic acid thiab lactic acid yog cov kua qaub xav tau thaum lub sijhawm silage fermentation. Formic acid yog siv rau hauv kev ua silage kom txo cov kab mob tsis xav tau thiab pwm loj hlob. Formic acid txo cov kab mob Clostridia uas yuav tsim cov butyric acid ua rau lwj. Ntxiv nrog rau kev tiv thaiv silages lwj, formic acid pab khaws cov protein, txhim kho kev sib sau ua ke, thiab khaws cov suab thaj. Formic acid yog siv ua tshuaj tua kab mob los ntawm cov neeg yug beekeepers.

2. Formic Acid yog ib yam khoom tsw qab uas yog kua thiab tsis muaj xim, thiab muaj ntxhiab tsw qab. Nws sib xyaw nrog dej, cawv, ether, thiab glycerin, thiab tau los ntawm kev tsim tshuaj lom neeg lossis kev oxidation ntawm methanol lossis formaldehyde.

3. Cov kua qaub formic tshwm sim hauv cov kab ntsaum thiab muv tom. Nws yog siv rau hauv kev tsim cov ntsev esters thiab ntsev, dyeing thiab ua tiav cov ntaub thiab ntawv, electroplating, kho tawv, thiab coagulating roj hmab latex, thiab kuj yog tus neeg sawv cev txo qis.
