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

(R) - (-) -1,2-Propanediol lulwelo olungenambala ukuya kumthubi olubonakalayo. (R) Amaqela e-hydroxyl kwisakhiwo se-1,2-propanediol ane-nucleophilicity ethile kwaye athambekele ekungeneni kwi-nucleophilic substitution reactions kunye ne-alkyl halides kunye ne-acyl halides ukufumana i-ether ehambelanayo kunye ne-ester derivatives. Ngenxa yokuba amaqela amabini e-hydroxyl akwindawo ezimeleneyo, anokuthi adibane ne-condensation kunye nee-aldehydes kunye nee-ketones ukwenza ii-aldehydes okanye iikhompawundi ze-aldehyde.

Isicelo

(R) - (-) -1,2-Propanediol ingasetyenziselwa njengento ekrwada kwii-resin ze-polyester ezingaxutywanga kwaye inokudibaniswa ne-glycerol okanye i-sorbitol njenge-agent emanzi kwi-cosmetics, i-toothpaste kunye nesepha. Isetyenziswa kwidayi yeenwele njengesilawuli sokufuma, i-homogenizer yeenwele, i-antifreeze, kunye nephepha leglasi, iplastiki, kunye namashishini amayeza.
