Puas yog ethyl acetate (CAS 141-78-6) thiab acetic acid (cas 64-19-7) zoo ib yam?

Ethyl acetate thiab acetic acid yog ob qhov sib txawv nrog cov qauv molecular sib txawv.

Cov khoom ntawm Ethyl Acetate thiab Acetic Acid

Ethyl Acetate: Kuj hu ua ethyl ethanoate,ethyl acetate hmoovyog ib qho organic compound nrog cov mis molecular C₄H₈O₂. Nyob rau hauv chav tsev kub, nws zoo li cov kua tsis muaj xim. Nws muaj qhov saj thiab tsw zoo ib yam li acetic acid, uas ua rau nws dav siv los ua cov kuab tshuaj thiab tsw qab. Nws tuaj yeem yaj ntau cov organic xws li cov pos hniav, resins, xim, thiab inks.

Acetic Acid: Acetic acid yog cov kua tsis muaj xim, pob tshab thiab ib hom organic acid nrog cov mis molecular C₂H₄O₂. Feem ntau hu ua vinegar acid, nws yog lub ntsiab acidic tivthaiv nyob rau hauv dog dig vinegar. Acetic acid yog ib qho tseem ceeb ntawm cov khoom siv raw thiab siv dav hauv kev lag luam xws li kev tsim tshuaj lom neeg, tshuaj, thiab zaub mov.

Molecular Structure ntawm Ethyl Acetate thiab Acetic Acid

Ethyl acetate thiab acetic acid sib txawv hauv cov qauv molecular. Cov ethyl acetate molecule muaj ob pawg: pawg acetyl (CH₃COO-) thiab pawg ethoxy (-OCH₂CH₃) txuas los ntawm cov pa atom, tsim cov compound nrog cov mis molecular C₄H₈O₂.

Acetic acid muaj ib pawg acetyl (CH₃COO-) thiab ib lub hydrogen atom (H+). Nws cov qauv zoo ib yam li cov pa roj carbon- pawg hydrogen txuas rau pawg carboxylic acid. Cov khoom no tau koom nrog covalent bonds, ua rau cov mis molecular C₂H₄O₂.

Kev siv Ethyl Acetate thiab Acetic Acid

Ethyl Acetate: Hauv kev lag luam, ethyl acetate yog siv dav hauv kev tsim cov rayon, tawv tawv, xim, nplaum, yas, inks, thiab lwm yam tshuaj.
Nws kuj yog siv los ua tus neeg sawv cev, muab cov txiv hmab txiv ntoo lossis khoom qab zib -zoo li aromas.
Tsis tas li ntawd, ethyl acetate yog cov khoom siv raw hauv kev tsim cov tshuaj thiab chiv.

Kev siv Ethyl Acetate

Acetic acid:Acetic acidmuaj cov ntawv thov thoob plaws ntau yam kev lag luam. Hauv kev lag luam khoom noj khoom haus, nws feem ntau yog siv los ua cov tshuaj tsw qab thiab acidulant, xws li hauv vinegar, soy sauce, thiab condiments.
Hauv kev siv tshuaj, nws yog siv los tsim qee yam tshuaj, tshuaj loog, thiab tshuaj tua kab mob. Hauv cov txheej txheem textile thiab luam ntawv, acetic acid tuaj yeem ua tus dyeing lossis luam ntawv tus neeg sawv cev.
Nws kuj tseem siv dav hauv kev lag luam tshuaj rau kev tsim cov yas, roj hmab, dyes, thiab coatings.
