benzoic acid

benzoic acid

Kuj hu ua: benzoic acid

Kev Txhais Lus: Cov mis tshuaj yog C6H5COOH, uas yog tsim los ntawm kev oxidation ntawm toluene. Nws feem ntau yog siv ua cov tshuaj preservative, tshuaj tua kab mob, thiab kuj siv ua tshuaj thiab tshuaj nruab nrab.

Khoom Siv: Cov Khoom Siv Tshuaj thiab Cov Khoom Siv

Cov lus sib xws: sodium benzoate, cholesteryl benzoate, khoom noj khoom haus preservative.

Benzoic acid thiab nws cov ntsev sodium (sodium benzoate) yog cov tshuaj preservatives uas siv rau hauv cov zaub mov. Nws muaj cov khoom siv antiseptic zoo tshaj plaws nyob rau hauv cov kua qaub thiab muaj cov nyhuv ntawm kev tiv thaiv kev loj hlob ntawm cov fungi, cov kab mob thiab pwm. Thaum siv ua tshuaj, benzoic acid feem ntau yog siv rau ntawm daim tawv nqaij ua ke nrog salicylic acid los kho cov kab mob ntawm daim tawv nqaij xws li ringworm. Benzoic acid yog cov khoom siv raw rau kev tsim cov tshuaj tua kab, cov xim zas, tshuaj, cov txuj lom, mordants thiab plasticizers. Nws kuj yog ib qho modifier rau polyamide resins thiab alkyd resins thiab ib qho inhibitor xeb rau cov khoom siv hlau. Tsis tas li ntawd, benzoic acid kuj tseem siv tau rau hauv cov fiber hluavtaws, resin, txheej, roj hmab thiab luam yeeb.

Sodium benzoate zoo ib yam li potassium sorbate. Benzoic acid thiab nws cov ntsev sodium tshwm sim ntuj hauv cov nroj tsuag (tshwj xeeb tshaj yog cov txiv hmab txiv ntoo), tab sis feem ntau tau txais los ntawm kev lag luam los ntawm kev tsim tshuaj lom neeg. Sodium benzoate muaj ntau yam kev siv ua cov tshuaj preservative thiab feem ntau siv rau hauv cov khoom noj (xws li vinegar, kua ntses, nqaij, ntses, cov khoom noj pickled, thiab lwm yam), dej haus (tshwj xeeb tshaj yog dej qab zib) thiab cov khoom siv tu tus kheej (dyes, tshuaj pleev ib ce, thiab lwm yam) thiab lwm yam lag luam, nws yog siv dav hauv cov tebchaws thoob ntiaj teb.

Ntxiv rau kev siv ua ib qho tshuaj preservative, benzoic acid kuj yog ib qho intermediate hauv organic synthesis. Cholesterol benzoate yog cov kua siv lead ua kua thaum ntxov tshaj plaws uas tib neeg pom thiab yog cov khoom tseem ceeb ntawm cov kua siv lead ua zaub. Nws tuaj yeem siv ua thermochromic kua siv lead ua tom qab sib xyaw nrog cholesterol nonanoate thiab cholesterol oleyl cawv carbonate, thiab siv dav hauv kev tiv thaiv kev ntim khoom cuav. Tsis tas li ntawd, cholesteryl benzoate kuj yog ib qho intermediate hauv kev tsim cov vitamin D3.

Methyl benzoate muaj nyob rau hauv cov roj clove, roj ylang-ylang thiab roj tuberose. Nws muaj ntxhiab tsw qab heev thiab feem ntau siv rau hauv kev npaj cov tshuaj tsw qab thiab cov roj tsw qab dag. Nws kuj tseem siv tau ua cov organic solvent. Ethyl benzoate muaj nyob rau hauv cov nplooj haus luam yeeb uas kho tau los ntawm cua sov, txiv duaj, txiv laum huab xeeb thiab tshuaj yej dub. Nws yog ib feem ntawm qee cov tsw qab ntuj thiab cov tsw qab tsim thiab siv tau los ua cov tsw qab txiv hmab txiv ntoo, thiab lwm yam. Propyl benzoate muaj nyob rau hauv cov txiv ntoo qab zib, cov qia clove, thiab butter. Nws muaj ntxhiab txiv ntoo lossis txiv hmab txiv ntoo thiab siv rau hauv cov khoom noj ua cov tsw qab tsim. Nws kuj muaj cov khoom tua kab mob thiab siv ua cov tshuaj tiv thaiv hauv cov tshuaj pleev ib ce.
