APAKAH MAKSUD MERCAPTIDE dalam CORSICA?
Thiol
Dalam kimia organik, thiol adalah sebatian organosulfur yang mengandungi kumpulan sulfihidril yang terikat karbon. Thiols adalah analog sulfur alkohol, dan perkataannya adalah portmanteau "thion" + "alkohol," dengan perkataan pertama yang berasal dari bahasa Yunani θεῖον = "sulfur." Kumpulan berfungsi -SH sendiri dirujuk sebagai sama ada kumpulan thiol atau kumpulan sulfhydryl. Ramai thiols mempunyai bau yang kuat menyerupai bawang putih. Thiols digunakan sebagai bahan bau untuk membantu pengesanan gas asli, dan "bau gas asli" adalah disebabkan bau thiol yang digunakan sebagai bau. Thiols sering dirujuk sebagai mercaptan. Istilah mercaptan / mərkæptæn / berasal dari penarik mercurium Latin kerana bon kumpulan thiolate sangat kuat dengan sebatian merkuri. Thiols bertindak balas dengan merkuri untuk membentuk mercaptides.
Definisi mercaptide dalam kamus Corsica
Takrifan mercaptide dalam kamus adalah garam mercaptan, yang mengandungi ion RS-, di mana R adalah kumpulan alkil atau aril.

Polymer Physics: From Suspensions to Nanocomposites and Beyond
Thiol reduced the platinum(IV) ions to platinum(II) before mercaptide precipitation
. The obtained platinum(II) dodecylmercaptide was a crystalline orange solid. The
mercaptide was separated by vacuum filtration and washed with ethyl alcohol.
