Kev piav qhia dawb los yog lub teeb daj crystalline hmoov.Yooj yim soluble nyob rau hauv methanol thiab ether, tsis yooj yim soluble nyob rau hauv dej kub, thiab yuav volatilized nrog dej vapor;phthalic acid yog tau los ntawm oxidation, uas yuav siv tau raws li intermediates ntawm cov tshuaj, cov ntaub ntawv photosensitive, tshuaj tua kab, thiab organic pigments.Feem ntau yog siv rau hauv kev tsim cov hemostatic aromatic acid, p-formonitrile, p-toluoyl chloride, cov ntaub ntawv photosensitive, thiab lwm yam. Nws yog siv nyob rau hauv cov organic synthesis intermediates thiab tshuaj tua kab kev lag luam los npaj bactericide phosphoramide, thiab nws kuj yuav siv tau nyob rau hauv naj hoom thiab zaj duab xis. .
Intermediates rau tshuaj, cov ntaub ntawv photosensitive, tshuaj tua kab thiab organic pigments.Feem ntau siv rau hauv kev tsim cov hemostatic aryl acid, p-methylonitrile, p-toluenyl chloride, cov ntaub ntawv photosensitive, thiab lwm yam. Siv nyob rau hauv organic synthesis intermediate, tshuaj tua kab kev lag luam los tsim fungicide phosphamide, kuj yuav siv tau nyob rau hauv cov txuj lom thiab zaj duab xis.
Dawb los yog lub teeb daj crystalline hmoov.Melting point 179-182 ° C.Kub taw tes yog 274-275 ° C.Yooj yim soluble nyob rau hauv methanol thiab ether, tsis yooj yim soluble nyob rau hauv dej kub, thiab yuav volatilized nrog dej vapor;phthalic acid yog tau los ntawm oxidation, uas yuav siv tau raws li intermediates rau tshuaj, photosensitive cov ntaub ntawv, tshuaj tua kab, thiab organic pigments.Feem ntau siv hauv kev tsim cov hemostatic aromatic acid, p-formonitrile, p-toluoyl chloride, cov ntaub ntawv photosensitive, thiab lwm yam.
Nws yog yooj yim soluble nyob rau hauv methanol thiab ether, tab sis hardly soluble nyob rau hauv dej kub, thiab yuav volatilized nrog dej vapor;phthalic acid yog tau los ntawm oxidation, uas yuav siv tau raws li intermediates rau tshuaj, photosensitive cov ntaub ntawv, tshuaj tua kab, thiab organic pigments.Feem ntau siv hauv kev tsim cov hemostatic aromatic acid, p-formonitrile, p-toluoyl chloride, cov ntaub ntawv photosensitive, thiab lwm yam.
