2 4-Dichloro-3-Methylbenzoic acid (CAS # 83277-23-0)

Taw qhia

3-Methyl-2,4-dichlorobenzoic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:

Zoo:

- Zoo li: tsis muaj xim crystalline khoom

- Solubility: soluble hauv cov kuab tshuaj organic xws li ethanol, ether thiab methylene chloride, insoluble hauv dej

Siv:

- Cov tshuaj tua kab: 3-methyl-2,4-dichlorobenzoic acid yog cov tshuaj tua kab dav dav uas siv tau los tswj kev loj hlob ntawm ntau hom nroj tsuag, xws li cov nyom ib puag ncig cov qoob loo xws li kale, legumes, thiab pob kws.

Txoj kev:

3-Methyl-2,4-dichlorobenzoic acid tuaj yeem npaj los ntawm chlorination ntawm p-methylanise ether (3-methylanisole). Txoj kev npaj tshwj xeeb tuaj yeem koom nrog cov kauj ruam hauv qab no:

Dissolve 3-methylanisole hauv anhydrous hydrochloric acid.

Sodium chlorite (NaClO) lossis potassium chlorite (KClO) tau ntxiv los ua cov tshuaj chlorine.

Cov tshuaj tiv thaiv sib tov yog nplawm ntawm qhov kub thiab txias, feem ntau ntawm 0-5 ° C.

Tom qab cov tshuaj tiv thaiv tiav lawm, cov sib tov yog lim los yog muab rho tawm kom tau 3-methyl-2,4-dichlorobenzoic acid khoom.

Cov ntaub ntawv kev nyab xeeb:

- 3-Methyl-2,4-dichlorobenzoic acid tuaj yeem ua rau muaj kev puas tsuaj rau ib puag ncig, thiab yuav tsum tau saib xyuas kev tswj xyuas kev siv thiab pov tseg cov khoom pov tseg.

- Kev sib cuag ncaj qha nrog cov khoom yuav ua rau khaus ntawm daim tawv nqaij, qhov muag, thiab ua pa, thiab kev sib cuag ncaj qha yuav tsum raug zam.

- Hnav cov khoom tiv thaiv tsim nyog xws li hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg thaum siv.

- Kev saib xyuas yuav tsum tau ua kom tsis txhob sib xyaw nrog lwm cov tshuaj thaum lub sijhawm khaws cia thiab tuav, thiab tsis txhob muaj hluav taws kub thiab kub.

- Thov nyeem thiab ua raws li cov ntawv txheeb xyuas kev nyab xeeb thiab cov lus qhia ua ntej siv.
