Khoom Description
Kev taw qhia thiab kev siv CAS:603-45-2| ROSOLIC ACID
Alias ntawm rose acid: resinous acid, rose acid, sawv acid, golden liab, sib sib zog nqus liab crystals nrog metallic luster. Rosaceae acid kuj muaj daj-xim av flakes nrog cov xim ntsuab tsaus ntsuab. Rosacetic acid yog yooj yim soluble nyob rau hauv cawv thiab nthuav tawm ib tug Golden daj kua; thaum soluble nyob rau hauv sodium hydroxide los yog poov tshuaj hydroxide tov, nws nthuav cov xim liab carmine; thaum soluble hauv concentrated sulfuric acid, 70% sulfuric acid, hydrochloric acid los yog perchloric acid, nws nthuav tawm daj rau txiv kab ntxwv kua; thiab nws yog me ntsis soluble hauv glacial acetic acid. , me ntsis soluble hauv ether thiab chloroform, yuav luag insoluble hauv (0.12%) thiab benzene. Lub Hom Phiaj Rose acid tuaj yeem siv los ua cov khoom zoo rau cov pa roj carbon dioxide hauv cov dej haus, thiab tseem tuaj yeem siv los paub qhov txawv ntawm tib neeg cov mis nyuj los ntawm nyuj mis nyuj. Rosacetic acid kuj yog xim nruab nrab. Cov kua qaub belongs rau hydroxytriphenylmethane dye. Nws tsis muaj nqi dyeing rau textile fibers. Nws yog tsuas yog siv los ua qhov taw qhia hauv analytical chemistry. Nws tus nqi pH discoloration ntau yog 6.2 txog 8.0, thiab xim hloov ntawm daj mus rau liab.
