1.The heptanal butyl mercaptal was synthesized with heptanal, sodium thiosuifate and 1bromobutane as raw materials.
正庚、代酸钠和溴代正丁烷为原料,合成了正庚正丁醇缩。
2.With sodium hyposulphite standard solution used in titration and starch developing agent as indicator,iron content can be determined.
代酸钠标准溶液漓定,淀粉显色为指示,可测定铁含量。
3.After comparison,sodium hyposulfite is the preferred absorbent,which the resultant has no influence on the environment with sodium hyposulfite over absorbed dose.
比较,代酸钠吸量大,生成物对环境没有影响,为首选吸。
4.Using sodium hydrosulphide or sodium thiosulfate as materials,the production cost of TGA is low.While,a high content of TGA can be obtained with thiourea as reactant.
