Polyethylene glycol phenyl ether (CAS # 9004-78-8)

Taw qhia

Phenol ethoxylates yog nonionic surfactants. Nws cov khoom tseem ceeb muaj xws li:

Cov tsos mob: Feem ntau tsis muaj xim lossis lub teeb daj ua kua.

Solubility: soluble nyob rau hauv dej thiab organic solvents, miscible nrog ntau yam.

Kev ua haujlwm saum npoo av: Nws muaj qhov ua haujlwm zoo ntawm qhov chaw, uas tuaj yeem txo qhov nro ntawm cov kua thiab ua kom cov dej ntub dej ntau ntxiv.

Kev siv tseem ceeb ntawm phenol ethoxylates suav nrog:

Kev lag luam siv: Nws tuaj yeem siv los ua cov dispersant rau dyes thiab pigments, tus neeg sawv cev ntub dej rau textiles, coolant rau metalworking, thiab lwm yam.

Muaj ob txoj hauv kev npaj tseem ceeb rau phenol ethoxylate:

Condensation cov tshuaj tiv thaiv ntawm phenol thiab ethylene oxide: phenol thiab ethylene oxide yog reacted nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim phenol ethoxyethylene ether.

Ethylene oxide yog ncaj qha condensed nrog phenol: ethylene oxide yog ncaj qha reacted nrog phenol thiab phenol ethoxylates yog npaj los ntawm condensation cov tshuaj tiv thaiv.

Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag, thiab yaug nrog dej kom ntau yog tias muaj teeb meem tshwm sim.

Tsis txhob nqus cov vapors los ntawm nws cov pa roj lossis cov kev daws teeb meem thiab ua haujlwm hauv qhov chaw uas muaj cua zoo.

Ua tib zoo tiv thaiv nws los ntawm kev sib cuag nrog cov oxidants muaj zog, acids thiab lwm yam khoom kom tsis txhob muaj kev phom sij txaus ntshai.

Ua raws li kev coj ua nyab xeeb rau kev siv thiab khaws cia, xws li hnav hnab looj tes tiv thaiv thiab tsom iav. Yog nqos los yog noj, nrhiav kev kho mob tam sim ntawd.
