1,8-Octanediol (CAS # 629-41-4) Taw qhia

1,8-Octanediol yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 1,8-octandiol:

Zoo:
1,8-Caprylyl glycol yog cov kua tsis muaj xim thiab pob tshab nrog lub qab zib. Nws muaj qhov tsis tshua muaj vapor siab thiab viscosity ntawm chav tsev kub thiab soluble hauv dej thiab feem ntau cov kuab tshuaj organic.

Siv:
1,8-Octanediol muaj ntau yam kev siv. Nws feem ntau yog siv los ua raw khoom rau softeners, plasticizers thiab lubricants.

Txoj kev:
1,8-Octanediol tuaj yeem npaj los ntawm oxidation ntawm octanol. Ib txoj hauv kev yog qhov catalytic oxidation cov tshuaj tiv thaiv ntawm octanol nrog oxygen, uas feem ntau siv tooj liab-chromium catalyst.

Cov ntaub ntawv kev nyab xeeb:
1,8-Octanediol yog ib qho kev nyab xeeb zoo nyob rau hauv cov xwm txheej. Kev nthuav tawm los yog nqus tau cov ntsiab lus siab ntawm 1,8-caprylydiol tuaj yeem ua rau khaus ntawm qhov muag, tawv nqaij, thiab ua pa. Thaum tuav 1,8-octanediol, tsom iav tiv thaiv, hnab looj tes thiab qhov ncauj qhov ntswg yuav tsum tau hnav kom muaj cua zoo. Saib xyuas kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog thiab cov khoom siv hluav taws xob tiv thaiv hluav taws los yog tawg. Thaum khaws cia thiab tuav 1,8-caprylydiol, ua raws li cov qauv kev nyab xeeb thiab cov kev cai.
