Khoom Description
25kg Isophthalic acid yog cov hmoov dawb crystalline hmoov lossis rab koob - zoo li siv lead ua nrog cov tshuaj formula C8H6O4 thiab qhov hnyav molecular ntawm 166.13. Nws yog yooj yim soluble nyob rau hauv cawv thiab glacial acetic acid, me ntsis soluble nyob rau hauv boiling dej tab sis insoluble nyob rau hauv dej txias, thiab yuav luag insoluble nyob rau hauv benzene thiab roj av ether.
25kg isophthalic acid lub melting point yog 341-343 degree, qhov ceev yog 1.507, thiab nws muaj sublimation. Nws yog cov tshuaj lom neeg tsawg, nyuaj rau yaj hauv dej, txog 25mg / 100g dej (25 degree), insoluble hauv benzene, toluene thiab roj av ether, tab sis soluble hauv ethanol, acetone thiab glacial acetic acid.

Lub cev thiab tshuaj lom neeg cov khoom ntawm isophthalic acid ua rau nws siv dav hauv ntau qhov chaw. Piv txwv li, nws yog siv los tsim alkyd resins, unsaturated polyester resins thiab lwm yam polymers thiab plasticizers, thiab tseem siv los tsim cov xim xim, coatings thiab polyester fiber dyeing modifiers thiab tshuaj. Hauv kev lag luam, isophthalic acid feem ntau yog tsim los ntawm kev siv meta-xylene li raw khoom, cobalt acetate li catalyst, acetaldehyde li txhawb, acetic acid ua hnyav, thiab qis-kub kua theem oxidation ntawm 120℃nyob rau hauv ib tug siab ntawm txog 0.6MPa. Tsis tas li ntawd, hydrolysis ntawm isophthalonitrile los yog oxidation ntawm meta-xylene nrog poov tshuaj permanganate kuj yog txoj hauv kev los tsim cov isophthalic acid.
Feem ntau, isophthalic acid nyob hauv txoj haujlwm tseem ceeb hauv kev lag luam tshuaj lom neeg vim nws lub cev thiab tshuaj lom neeg tshwj xeeb thiab ntau yam kev siv, thiab tau ua haujlwm tseem ceeb rau kev tsim kho ntawm ntau lub lag luam.
