Dab tsi yog Pesticide Intermediates?

Cov khoom tsim los ntawm kev ua liaj ua teb raw cov ntaub ntawv yog ib qho nruab nrab nruab nrab uas muab ob los yog ntau yam khoom ua ke. Hauv cov tshuaj tua kab, nws tuaj yeem nkag siab tias yog tus neeg sawv cev sib koom ua ke, uas yog cov khoom siv los tsim cov tshuaj tua kab nruab nrab.
Kuj tseem hu ua organic intermediates. Siv cov khoom siv roj av los yog cov khoom siv roj av ua cov khoom siv raw los tsim cov khoom nruab nrab xws li dyes, tshuaj tua kab, tshuaj, resins, additives, plasticizers, thiab lwm yam. Vim nws thawj zaug siv hauv kev tsim cov dyes, Z tseem hu ua dye intermediate.
Nws yog tsim los ntawm cov tshuaj tiv thaiv xws li sulfonation, alkali melting, nitration, txo, thiab lwm yam ntawm cyclic compounds xws li benzene, naphthalene, anthracene, thiab lwm yam.
Piv txwv li, benzene yog nitrated rau nitrobenzene, uas yog txo mus rau aniline. Aniline tuaj yeem ua cov tshuaj dyes, tshuaj, vulcanization accelerators, thiab lwm yam. Nitrobenzene thiab aniline yog ob qho tib si nruab nrab.
Nws yog tsim los ntawm dehydrogenation, polymerization, halogenation, hydrolysis, thiab lwm yam kev cuam tshuam ntawm acyclic compounds xws li methane, acetylene, propylene, butane, thiab butene.
Piv txwv li, butane los yog butene tuaj yeem dehydrogenated rau hauv butadiene, uas tuaj yeem ua rau cov roj hmab hluavtaws, hluavtaws fibers, thiab lwm yam. Butadiene yog qhov nruab nrab.
Intermediates xa mus rau cov khoom lag luam ib nrab, uas yog cov khoom nruab nrab hauv kev tsim cov khoom lag luam. Piv txwv li, los tsim cov khoom, nws tuaj yeem tsim los ntawm cov khoom nruab nrab kom txuag tau cov nqi. Kev tsim tshuaj yuav tsum muaj ntau yam tshuaj tshwj xeeb, uas yog feem ntau tsim los ntawm kev lag luam kws tshuaj nws tus kheej. Txawm li cas los xij, nrog kev sib koom ua ke ntawm kev ua haujlwm ntawm kev sib raug zoo thiab kev nce qib ntawm cov thev naus laus zis ntau lawm, kev lag luam tshuaj tau hloov qee cov tshuaj intermediates rau cov lag luam tshuaj rau kev tsim khoom. Pharmaceutical intermediates yog cov khoom siv tshuaj zoo, thiab kev tsim cov tshuaj intermediates tau dhau los ua kev lag luam loj hauv kev lag luam tshuaj lom neeg thoob ntiaj teb.
