Oct 21, 2021
Tus txheeb ze ntom ntom: 0.9337
Curing point: -40 ° C
Refractive index: 1.4831
Flammable: Flammable. Cov khoom lag luam dav dav yog sib xyaw ntawm peb isomers. α-Terpineol muaj peb hom isomers optical: levorotatory, dextrorotatory, thiab racemic. (+)-α-lub cev muaj nyob rau hauv cov roj yam tseem ceeb xws li turpentine roj, cardamom roj, qab zib txiv kab ntxwv roj, nutmeg roj; (-)-α-lub cev muaj nyob rau hauv cov roj yam tseem ceeb xws li Pine koob roj, cinnamon nplooj roj, txiv qaub roj, thiab dawb txiv qaub roj nruab nrab; (±)-α-lub cev muaj nyob rau hauv cov roj yam tseem ceeb xws li geraniol thiab eucalyptus roj; γ-lub cev tau pom nyob rau hauv Tibet cypress nplooj roj. Terpineol yog cov kua tsis muaj xim tsis muaj xim. Distillation ntau yam 214 ~ 224 ℃ (101.3kPa). Insoluble hauv dej, soluble hauv cov kuab tshuaj organic xws li ethanol. Nws muaj cov tshuaj tsw qab zoo li Pittosporum, qab zib lilac thiab lily ntawm hav fragrance. Soluble hauv ethanol, me ntsis soluble hauv dej thiab glycerin. 1 feem ntawm terpineol tuaj yeem yaj hauv 2 qhov chaw (ntim) ntawm 70% ethanol tov.
Kev npaj: Siv cov roj turpentine ua raw khoom, ntxiv ib qho me me ntawm lub tiaj tus ntxiv rau sulfuric acid ua ib qho emulsifier, thiab nqa tawm cov tshuaj tiv thaiv dej ntawm chav tsev kub kom ua cov khoom tseem ceeb pinene hauv cov roj turpentine tsim hydrated terpene diol, uas yog lub cev qhuav dej kom tau txais. crude terpineol, uas yog tau los ntawm fractional distillation.
