APAKAH MAKSUD CHLOROHYDRIN dalam CORSICA?
Halohidrin
Halohidrin atau haloalcohol adalah jenis sebatian organik atau kumpulan berfungsi di mana satu atom karbon mempunyai substituen halogen, dan atom karbon bersebelahan mempunyai substituen hidroksil. Oleh itu, ia berasal dari alkohol dicirikan oleh kehadiran kedua-dua kumpulan fungsional hidroksil dan kumpulan berfungsi halogen. Haloalkohol, terutama alkohol dan bromoalkohol biasanya disintesis oleh halogenasi alkena dalam kehadiran air atau alkohol. Sebagai penutupan cincin intramolekul di antara karbon yang mengandungi dua kumpulan berfungsi boleh diinduksi dengan mudah melalui tindak balas dengan asas untuk memberikan epoksida, haloalkohol berguna sebagai perantara dalam sintesis kimia. Halohidrin terbentuk daripada alkena dalam reaksi pembentukan halohidrin atau dari epoksida oleh asid hidrohalik. Di hadapan asas, seperti kalium hidroksida, halohidrin mungkin menjalani reaksi SN2 dalaman untuk membentuk epoksida. Ini adalah tindak balas tindak balas pembentukan dari epoksida. Epoksidasi dalam sistem biologi boleh dipangkin oleh halohidrin dehalogenase. Mereka digunakan kebanyakannya dijumpai untuk tindak balas Penambahan, semasa menjadi Anti dan Markovnikov.
Definisi chlorohydrin dalam kamus Corsica
Takrifan chlorohydrin dalam kamus adalah mana-mana sebatian organik yang mengandungi kumpulan hidroksil dan atom klorin. Takrifan lain chlorohydrin adalah cecair hygroscopic tidak stabil yang digunakan terutamanya sebagai pelarut; 3-chloropropane-1,2-diol. Formula: CH2OHCHOHCH2Cl.
