Taw qhia
Glutaraldehyde, tseem hu ua valeraldehyde. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm glutaraldehyde:
Zoo:
Glutaraldehyde yog cov kua tsis muaj xim nrog cov ntxhiab tsw tsw. Nws reacts nrog huab cua thiab lub teeb thiab yog volatile. Glutaraldehyde yog me ntsis soluble hauv dej tab sis soluble nyob rau hauv feem ntau cov organic solvents.
Siv:
Glutaraldehyde muaj ntau yam kev siv. Nws tuaj yeem siv los ua cov tshuaj nruab nrab hauv kev lag luam rau kev tsim ntau yam tshuaj. Piv txwv li, nws tuaj yeem siv rau hauv kev sib txuas ntawm cov tshuaj tua kab, flavors, cog kev loj hlob regulators, thiab lwm yam.
Txoj kev:
Glutaraldehyde tuaj yeem tau txais los ntawm acid-catalyzed oxidation ntawm pentose lossis xylose. Txoj kev npaj tshwj xeeb suav nrog reacting pentose lossis xylose nrog cov kua qaub, thiab tau txais cov khoom siv glutaraldehyde tom qab oxidation, txo thiab kev kho lub cev qhuav dej.
Cov ntaub ntawv kev nyab xeeb:
Glutaraldehyde yog ib qho tshuaj lom neeg thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum tuav glutaraldehyde, cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav kom muaj cua zoo. Nws yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab qhov chaw kub, vim glutaraldehyde yog volatile thiab muaj kev pheej hmoo ntawm combustion. Thaum siv thiab khaws cia, yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb uas yuav tsum tau ua kom muaj kev nyab xeeb thiab tiv thaiv kev sib tsoo.
