五氯苯甲氰是合成农药、染料及医药产品的有用中间体。五氯苯甲氰合成新工艺采用苯甲氰为原料，经过氯化、吸收、离心、干燥过程，得到五氯苯甲氰。在我国五氯苯甲氰的合成技术及工业生产均为空白，五氯苯甲氰合成新工艺通过了湖南省科委鉴定，为国内首创，填补国内空白。 Pentachloro-benzonitrile is the valuable precursor for pestcide, dye and medicine. Benzonitrile is used as raw material in this new technique of pentachloro-benzonitrile synthesis, and pentachloro-benzonitrile is obtained through chlorization, absorption, centrifugalization and drying process. The science and technology commission of Hunan appraises this new process, which is the pioneering technique and fill in the blank in China.
