Product description:Adjacent chlorotoluene put in reaction kettle, using ultraviolet light, reaction temperature 100 ℃, ventilation with chlorine to chloride reaction, deepen the chlorination depth to generate alpha, alpha, alpha, 2-4 chloro toluene, or with adjacent chlorotoluene as raw material, by azodiisobutyronitrile chloride as catalyst, also can get alpha, alpha, alpha, 2-4 chloro toluene, then the product into the hydrolysis kettle, add a little acid hydrolysis makes it generate chlorobenzene formyl chloride, 2 - chlorobenzoic acid hydrolysis depth is available.Dyes, pesticide, pharmaceutical intermediates and used in the manufacture of chlorpromazine and anti-inflammatory drugs such as spirit, is used as adhesive and coating preservative and organic synthesis of raw materials, can also be used to dye and color film. Also can be used as a fungicide. Adjacent chlorobenzoic acid is alkaline standard reagent method and iodine method.
