Yam Nruab Nrab

Qib Nruab Nrab hais txog cov khoom lag luam semi-tiav uas yog cov khoom lag luam ntawm cov khoom tsim tawm. Piv txwv li, los tsim cov khoom lag luam, nws tuaj yeem tsim tawm hauv nruab nrab, uas txuag nqi.

Qhov nruab nrab yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov pa roj carbon monoxide xws li benzene, naphthalene lossis anthracene los ntawm sulfonation, alkali fusion, nitration, txo lossis lwm yam. Piv txwv li, benzene yog nitrated rau nitrobenzene, thiab tom qab ntawd txo qis rau aniline, uas tuaj yeem ua tshuaj lom neeg rau hauv dyes, tshuaj, vulcanization accelerator, thiab cov zoo li. Ob leeg nitrobenzene thiab aniline yog intermediates.

Nws tseem tau txais los ntawm kev ua kom cov acyclic tebchaw xws li methane, acetylene, propylene, butane, butylene, thiab lwm yam los ntawm dehydrogenation, polymerization, halogenation, hydrolysis, thiab cov zoo li. Piv txwv, butane lossis butene yog dehydrogenated rau butadiene, thiab butadiene tuaj yeem raug tshuaj rau hauv cov roj hmab hluavtaws, cov khoom hluavtaws, thiab cov zoo li. Butadiene yog ib nrab.

Keeb kwm xa mus rau cov khoom lag luam ua nruab nrab tsim nyob rau hauv cov txheej txheem ntawm cov khoom siv tshuaj tua kab xws li tshuaj tsw qab, dyes, resins, chaw muag tshuaj, yas, roj hmab nrawm, thiab lwm yam los ntawm cov roj av tar lossis cov khoom siv roj av. Nws yog tam sim no dav xa mus rau raws li ntau yam intermediates tau txais thaum lub sij hawm organic synthesis.
