Cov Ntawv Thov
1.1 Tshuaj hauv nruab nrab
4-metHebYBENTBENTBENTBENTBENTBENCY yog siv dav ua lub tsev thaiv lossis tiv thaiv ib pawg hauv cov tshuaj saptthesis. Nws plays lub luag haujlwm hauv:
Kev npaj ntawm cov khoom xyaw cov tshuaj muaj zog (APIS)
Kev tiv thaiv cawv cawv thiab cov amine pab pawg thaum lub sij hawm multiistep synthesis
Nruab Nrab hauv synthesis ntawm cov tshuaj nrog cov tshuaj tiv thaiv kev txhawb nqa, tshuaj tiv thaiv kab mob, lossis cov tshuaj tua kab mob
1.2 Kev tiv thaiv pab pawg hauv synthes
P-methoxyBenzyl (PMB) pawg tau muab los ntawm cov compound no yog ib pab tiv thaiv nrov rau:
Cawv
Tus kuv noj
Nws muaj cov kua qaub ruaj khov thiab yooj yim cleavage nyob rau hauv kev mob oxidation me me lossis acidic tej yam kev mob (piv txwv li, siv ddq), ua rau nws zoo tshaj plaws rau kev siv hauv Peptide, carbohydrate, thiab nucleoside synthesis.
1.3 tsw thiab kev lag luam ntses
Vim nws cov me, qab ntxiag duab profile (zoo ib yam li kev ua tsis zoo lossis muaj cov ntawv hauv), nws yog siv hauv:
Cov tshuaj txhuam yeeb yam
Flagers
Aroma sib xyaw hauv cov khoom siv (naj hoom, soaps, tshuaj pleev ib ce)
1.4 agnchemical intermediate
Siv nyob rau hauv synthesis ntawm cov tshuaj tua kab, tshuaj tua kab, thiab fungicides. Nws ua haujlwm ua tus qauv tseem ceeb lossis pab pawg tiv thaiv hauv agochnical R & D.
1.5 polymer thiab cov khoom txuj ci
Caws cawv yog siv rau hauv cov polymer synthes-uas cov tswv yim uas muaj cov neeg muaj kuab phom, UV nqus, lossis ua haujlwm ua haujlwm zoo rau cov neeg thib kawg.
Cov txiaj ntsig
2.1 siab reactivity rau derivatization
Cov pab pawg Benzylic Cawv tso cai rau kev hloov pauv yooj yim rau hauv:
Lus coj neeg
Kaum ntxiv
Cog
Qhov no ua rau nws muaj feem cuam tshuam ntau rau cov khoom siv tshuaj tua hluavtis.
2.2 Kev Tiv Thaiv Kev Tiv Thaiv Zoo (PMB)
PMB pawg yog:
Yooj yim rau nruab (ntawm cov tshuaj tiv thaiv yooj yim)
Ruaj khov raws li acidic thiab yooj yim
Yooj yim muab tshem tawm nrog oxidants lossis lewis acids tsis muaj kev puas tsuaj molecules
2.3 Cov Khoom Siv Lub Cev Khoom Siv Lub Cev
Tsawg melting thiab boiling ntsiab lus
Soluble nyob rau hauv feem ntau cov emolic
Mob me thiab tswj tau belling profile rau muaj synthesis
2.4 Biocomparble thiab biodegradable Xwm
Qhov sib xyaw yog cov ntxhiab tab sis tsis dhau toxic, ua rau nws haum rau hauv cov kws tshuaj thiab cov qauv pleev xim rau hauv cov xwm txheej tswj hwm.
Tag
4-methoxyBenylenyyl cawv (CAS 105-13-5) yog qhov tseem ceeb tshaj plaws hauv kev lag luam thiab kev tshawb fawb txog cov khoom siv hluav taws xob, thiab cov nqi hluav taws xob ua ib pawg tiv thaiv. Nws plays lub luag haujlwm tseem ceeb hauv cov hluavtaws ntawm cov tshuaj, agnchemicals, thiab yog siv nyob rau hauv cov tshuaj tsw qab thiab cov khoom qab.
