Iyini i-(R)-(-)-1,2-Propanediol CAS 4254-14-2?

(R) - (-) -1,2-Propanediol uketshezi olubonisa ngale olungenambala ukuya kokuphuzi okuphaphathekile. (R) Amaqembu e-hydroxyl esakhiweni se-1,2-propanediol ane-nucleophilicity ethile futhi athambekele ekubhekaneni nokusabela kokushintshwa kwe-nucleophilic nge-alkyl halides nama-acyl halides ukuze athole okuphuma kokuphuma kwe-ether okuhambisanayo ne-ester. Ngenxa yokuthi amaqembu amabili e-hydroxyl asezindaweni eziseduze, angabhekana nokusabela kwe-condensation nge-aldehydes nama-ketone ukuze akhe ama-aldehydes noma ama-aldehyde compounds.

Isicelo

(R) - (-) -1,2-Propanediol ingasetshenziswa njengento eluhlaza yezinhlayiya ze-polyester ezingasetshenzisiwe futhi ingahlanganiswa ne-glycerol noma i-sorbitol njenge-ejenti yokumanzisa ku-cosmetics, umuthi wamazinyo, nensipho. Isetshenziswa kudayi wezinwele njengesilawuli somswakama, i-homogenizer yezinwele, i-antifreeze, kanye nasephepheni lengilazi, i-plasticizer, nezimboni zemithi.
