Taw qhia

Resorcinol tseem hu ua 2,3,5-trihydroxyanisole. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm resorcinol:

Zoo:

- Cov tsos mob: Resorcinol yog dawb mus rau daj daj crystalline khoom.

- Solubility: Resorcinol yog soluble hauv dej, ethanol thiab ether solvents.

Siv:

- Cov tshuaj tua kab mob: Resorcinol muaj cov tshuaj tua kab mob zoo thiab tuaj yeem siv los ua cov tshuaj tua kab mob, feem ntau siv hauv cov ntoo, ntawv, xim thiab lwm yam tshuaj tua kab mob.

- Synthetic dye intermediates: Lawv muaj ntau pawg hydroxyl hauv lawv cov qauv thiab tuaj yeem siv los ua ke cov nruab nrab ntawm cov organic tebchaw xws li dyes thiab fragrances.

- Lwm yam kev siv: Resorcinol kuj tuaj yeem siv los ua cov tshuaj tua kab mob thiab tshuaj tua kab mob hauv cov ntaub ntawv xws li cov khoom siv hluavtaws, roj hmab, thiab cov yas.

Txoj kev:

Resorcinol tuaj yeem npaj tau ntau txoj hauv kev, thiab ib txoj kev siv feem ntau yog kom tau nws los ntawm kev ua haujlwm phenol thiab hydrazine hydrate nyob rau hauv acidic tej yam kev mob.

Cov ntaub ntawv kev nyab xeeb:

- Phloroglucinol yog tshuaj lom rau tib neeg lub cev, thiab ntau dhau los yog nqus tau pa tuaj yeem ua rau tawv nqaij, qhov muag, thiab ua pa.

- Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog thiab muaj zog acids thaum tuav thiab khaws cia kom tsis txhob muaj tshuaj lom neeg txaus ntshai.

- Cov khoom siv tiv thaiv tus kheej xws li hnab looj tes, tsom iav, thiab daim npog ntsej muag yuav tsum hnav kom zoo thaum siv resorcinol thiab zam kev sib cuag lossis nqus pa.

- Ua raws li kev tuav thiab pov tseg kom raug kom txo tau cov pa phem rau ib puag ncig.
