Cov Qauv Zoo rau Oxalic Acid (Tus Qauv Hauv Tebchaws)
Oxalic acid, tseem hu ua ethanedioic acid, muaj cov qauv formula HOOCCOOH thiab molar mass ntawm 126.07. Nws feem ntau muaj nyob rau hauv daim ntawv dihydrate, zoo li cov xim tsis muaj xim pob tshab lossis hmoov dawb, tsis muaj ntxhiab nrog saj qaub. Nws muaj ob daim ntawv siv lead ua: α-form (rhombic) thiab β-form (monoclinic). Lawv cov ntsiab lus yaj thiab qhov sib piv ntawm qhov ceev (ntawm 17 ° C / 4 ° C) yog: α-form ntawm 189.5 ° C nrog qhov ceev ntawm 1.900; β-form ntawm 182 ° C nrog qhov ceev ntawm 1.895. Thaum raug rau huab cua qhuav lossis cua sov, nws poob nws cov dej ntawm crystallization. Oxalic acid yog volatile thiab sublimes yooj yim: nws pib sublime ntawm 100 ° C, sublimes sai ntawm 125 ° C, thiab sublimes dav dav thaum pib decompose ntawm 157 ° C. Nws yaj tau hauv dej kub thiab ethanol, yaj me ntsis hauv dej txias, yaj me ntsis hauv diethyl ether, thiab tsis yaj hauv benzene thiab chloroform. Raws li cov organic acid muaj zog, oxalic acid dhau los ua cov tshuaj tiv thaiv neutralization nrog cov hauv paus.
