OBSHCHEYe OPISANIYe I PRIMENENIYe

DIBUTIL OKSALAT (takzhe nazyvayemyy etandiovoy kislotoy) predstavlyayet soboy bestsvetnoye, kristallicheskoye, toksichnoye organicheskoye soyedineniye, prinadlezhashcheye k semeystvu dikarbonovykh kislot; plavleniye pri 187 ° C; rastvorim v vode, spirte i efire. On vstrechayetsya v forme soley metallov (obychno kal'tsiya ili kaliya) vo mnogikh rasteniyakh. V promyshlennykh masshtabakh on proizvoditsya putem nagrevaniya formiata natriya v prisutstvii shchelochnogo katalizatora s obrazovaniyem oksalata natriya, kotoryy pri obrabotke sernoy kislotoy dolzhen prevrashchat'sya v svobodnuyu shchavelevuyu kislotu. Yego takzhe poluchayut putem okisleniya uglevodov azotnoy kislotoy, nagrevaniya opilok yedkimi shchelochami ili fermentatsii sakharnykh rastvorov v prisutstvii opredelennykh form. Shchavelevaya kislota - yedinstvennoye vozmozhnoye soyedineniye, v kotorom dve karboksil'nyye gruppy soyedineny napryamuyu; po etoy prichine shchavelevaya kislota yavlyayetsya odnoy iz samykh sil'nykh kislot v organicheskikh soyedineniyakh. V otlichiye ot drugikh karbonovykh kislot, shchavelevaya kislota (i murav'inaya kislota) legko okislyayetsya i soyedinyayetsya s kal'tsiyem, zhelezom, natriyem, magniyem ili kaliyem s obrazovaniyem meneye rastvorimykh soley, nazyvayemykh oksalatami. Shchavelevaya kislota i oksalaty polezny v kachestve vosstanoviteley dlya fotografiy, otbelivaniya i udaleniya rzhavchiny. Oni shiroko ispol'zuyutsya v kachestve ochishchayushchego agenta v farmatsevticheskoy promyshlennosti, osaditelya pri obrabotke redkozemel'nykh metallov, otbelivayushchego agenta v tekstil'noy i derevoobrabatyvayushchey promyshlennosti, sredstva dlya udaleniya rzhavchiny dlya obrabotki metallov, shlifoval'nogo agenta, ochistki stochnykh vod. kislotnyye poloskaniya v prachechnykh i udaleniye nakipi s avtomobil'nykh radiatorov. Shchavelevaya kislota, alkilovyye efiry ispol'zuyutsya v kachestve rastvoriteley; plastifikatory; ochistitel' ot ostatkov polimerov; dispergator pigmentov; promezhutochnyye produkty dlya barbituratov, vitaminov, agrokhimikatov i drugikh organicheskikh soyedineniy.
