Cov Ntawv Thov
(S) - 1,2-propanediol carbonate yog feem ntau nyob rau hauv synching-carbonate, cov nplaum, thiab biodegradable plastics. Nws chairality ua rau nws tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev ua luam tawm cov tshuaj polymers thiab zoo rau cov tshuaj thiab cov ntawv thov tshuaj tshwj xeeb. Qhov sib txuas kuj tseem siv nyob rau hauv cov synthic synthesis rau kev npaj cov pa roj carbonivalized, carbamic, thiab lwm yam heterocyclic derivatives. Ib qho ntxiv, nws pabcuam ua cov kuab tshuaj thiab reagent hauv cov synthesis, ua rau kev tsim kho ntawm enantioselective cov kev coj noj coj ua thiab kev tsim cov chairal intermediates. Hauv kev tshawb fawb thiab kev loj hlob, nws yog siv los kawm biodegradable thiab cov ntaub ntawv muaj zog polymer, txhawb kev hloov pauv tshiab hauv cov ntaub ntawv zoo.
Cov txiaj ntsig
Cov txiaj ntsig ntawm (s)- 1,2-}}}}}}}}} cov nkauj, cov tshuaj lom neeg sib xyaw ua ke, thiab ib puag ncig compatibility. Nws cyclic qauv tso cai rau tswj polymerization thiab kev ua haujlwm, ua kom cov kev ua tau zoo, biodegradable, thiab pib ua haujlwm polymers. Nws cov biodegradity thiab tsawg toxicity ua nws haum rau kev siv khoom siv kom ruaj khov, sib thooj nrog cov ntsiab cai ntsuab. Qhov sib xyaw ua ke kuj muab cov kev ua kom siab thiab solubility hauv cov khoom siv organic, pab nws cov tshuaj hloov hluav taws xob ntau. Nws chairality muab cov cib fim rau enantioselective synthesis, ua rau muaj kev cuam tshuam thiab cov ntaub ntawv tshwj xeeb. Tsis tas li ntawd, nws ntau ntau yam txo qhov kev xav tau rau cov kev xav tau tshwj xeeb lossis cov txheej txheem hluavtaws nyuaj, txhim kho kev ua haujlwm thiab raug nqi hauv kev lag luam.
