5.This paper reviews the research and development of phosgene Derivates,including diphenyl ketone,chlorocarbonate,isocya-nate,acyl chloride and carbonates.
13.Under supergene process influencing, kaolinites invered dickites, siderite were been ferritization, part of carbonate mineral have been dissoluted producing calcite.
14.A tectno-magmatic province in relationship with the Dalimu and Sino-Korean paraplatforms defines two giant hyperalkaline to alkaline to carbonate mineralization belts.
15.We have observed similar protection and viability with other water-insoluble compounds such as calcium alginate, dimethylglyoxime, zinc carbonate, barium carbonate, and 1-aminoanthraquinone.
16.10.basement and unmetamorphosed terrigenous shallow carbonate rock in the Austria Alps -South Alps obduc-tion nappe and radiolarian silicalite in fault basins.
