Taw qhia
4- Isopropylphenol.
Zoo:
Cov tsos mob: tsis muaj xim lossis yellowish crystalline khoom.
Smell: Muaj cov ntxhiab tsw tshwj xeeb.
Solubility: soluble hauv ether thiab cawv, me ntsis soluble hauv dej.
Siv:
Kev sim tshuaj: siv los ua cov kuab tshuaj thiab cov nruab nrab hauv kev sib txuas ntawm cov organic sib txuas.
Txoj kev:
4-Isopropylphenol tuaj yeem npaj tau los ntawm ob txoj hauv qab no:
Isopropylphenyl acetone txo cawv txoj kev: 4-isopropylphenol yog tau los ntawm kev txo isopropylphenyl acetone cawv nrog hydrogen nyob rau hauv lub xub ntiag ntawm catalyst.
Polycondensation txoj kev ntawm n-octyl phenol: 4-isopropylphenol yog tau los ntawm polycondensation cov tshuaj tiv thaiv ntawm n-octyl phenol thiab formaldehyde nyob rau hauv acidic tej yam kev mob, thiab ces ua raws li kev kho mob tom ntej.
Cov ntaub ntawv kev nyab xeeb:
4-Isopropylphenol ua rau khaus thiab tej zaum yuav ua rau khaus ntawm qhov muag, tawv nqaij, thiab ua pa, thiab yuav tsum zam.
Thaum siv, yuav tsum tau saib xyuas kom tsis txhob nqus nws cov plua plav lossis vapors, thiab cov cuab yeej tiv thaiv tsim nyog yuav tsum tau hnav kom muaj cua zoo.
Thaum khaws cia thiab tuav, kev sib cuag nrog oxidants thiab muaj zog acids yuav tsum tau zam, thiab nyob rau tib lub sij hawm, kom deb ntawm ignition thiab kub ib puag ncig.
Nyob rau hauv rooj plaub ntawm kev sib chwv los yog kev sib tsoo, nrhiav kev kho mob tam sim ntawd. Yog tias ua tau, nqa lub thawv khoom lossis daim ntawv lo rau lub tsev kho mob kom paub meej.
Ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam thaum siv lossis tuav cov tshuaj no.
