Tom ntej: Octadecyl Trimethyl Ammonium Chloride CAS 112-03-8
Trimethylstearylammonium chloride feem ntau pom muaj xim dawb rau cov khoom dawb los yog hmoov. Nws yog quaternary ammonium compound uas feem ntau yog siv los ua surfactant lossis emulsifier hauv ntau daim ntawv thov. Cov tsos mob yuav txawv me ntsis nyob ntawm seb tus qauv tsim thiab purity ntawm qhov sib xyaw, tab sis feem ntau nws tseem nyob hauv daim ntawv no ntawm chav tsev kub.
Vim nws cov qauv quaternary ammonium, trimethylstearylammonium chloride feem ntau yog soluble hauv dej, tshwj xeeb tshaj yog thaum kub. Nws tuaj yeem ua rau cov kuab tshuaj organic xws li ethanol thiab methanol. Txawm li cas los xij, nws cov solubility tuaj yeem sib txawv nyob ntawm cov xwm txheej tshwj xeeb xws li qhov kub thiab txias. Feem ntau, nws yog ntau soluble nyob rau hauv polar solvents tshaj nyob rau hauv non-polar solvents.

Vanillyl butyl ether CAS 82654-98-6
Vanillyl butyl ether yog cov tshuaj sib xyaw uas feem ntau tsis muaj xim rau cov kua daj daj. Nws muaj qab zib vanilla tsw, uas yog yam ntxwv ntawm vanillin-derived compounds. Cov tshuaj feem ntau yog siv rau hauv kev siv tshuaj tsw qab thiab tshuaj tsw qab. Nyob rau hauv cov nqe lus ntawm nws lub cev muaj zog, nws yuav muaj ib tug kuj tsis tshua muaj viscosity thiab ib tug nruab nrab boiling point, uas yog ib tug ntawm cov ether tebchaw.
Vanillyl butyl ether feem ntau suav hais tias yog soluble hauv cov kuab tshuaj organic xws li ethanol, acetone, thiab lwm yam tsis muaj polar solvents. Txawm li cas los xij, vim nws pawg hydrophobic butyl, nws muaj kev txwv tsis pub solubility hauv dej.

4 4 oxybisbenzoic chloride / DEDC / cas 7158-32-9
4 4 Oxybis (benzoyl chloride) yog ib qho tshuaj lom neeg uas feem ntau tshwm sim raws li cov khoom dawb mus rau cov khoom dawb.
DEDC yog ib qho derivative ntawm benzoic acid thiab muaj ob benzoic acid moieties txuas nrog ether daim ntawv cog lus (lub "oxygen" moiety).
Cov tshuaj no feem ntau siv rau hauv cov organic synthesis thiab tej zaum yuav muaj cov qauv crystalline.
