APAKAH MAKSUD XANTHIC ACID dalam CORSICA?
Xanthate
Xanthate biasanya merujuk kepada garam dengan formula ROCS2-M +. Nama xanthates berasal dari Yunani ξανθός, yang bermaksud "kekuningan, emas", dan kebanyakan garam xanthate adalah kuning. Sebatian organosulfur ini penting dalam dua bidang, pengeluaran selofan dan polimer yang berkaitan dari selulosa dan kedua dalam perlombongan untuk pengambilan bijih tertentu. Mereka juga perantaraan serba boleh dalam sintesis organik. Xanthates juga merujuk kepada ester asid xanthic. Ester-ester ini mempunyai struktur ROCSR '.
