Storage method<\/h2>\n
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from oxidants, acid anhydrides and acid chlorides, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills. <\/p>\n
2. The wooden box outside the glass bottle is lined with padding or an iron drum. Store in a cool, ventilated warehouse; load and unload with care when handling to prevent damage to the container. <\/p>\n<\/p>\n
Synthesis method<\/h2>\n
Put 2,3,5,6-tetrachlorobenzene, solid alkali, and methanol into the autoclave, control the temperature at 135-152\u00b0C, and the pressure at 0.5-1.4MPa, and keep it for 14 hours. The reaction solution is cooled to 60\u00b0C, methanol is recovered by distillation, the residual liquid is released, cooled for crystallization, and filtered. Dissolve the crystals in water, heat to 70\u00b0C, add insurance powder, adjust pH = 9.2-9.6, add activated carbon, and decolorize at 95\u00b0C for half an hour. Filter, cool the filtrate to below 15\u00b0C, add hydrochloric acid to pH=2-3, filter out 2,4,5-trichlorophenol, and dry at 45\u00b0C to obtain the finished product. <\/p>\n<\/p>\n
Purpose<\/h2>\n
Used as fungicide and gas chromatography comparison sample. <\/p>\n<\/p>\n
