Product description:1. Used in the synthesis of benzoyl urea pesticides fluoride bell urea, kill fluid of intermediates such as urea, a short cycling and sulfonylurea herbicides, benzyl its cycling, pyrazole its cycling of intermediates, etc. 2. Oxalyl chloride is a widely used preparation carbonyl chloride and phosphoryl chloride, chlorinated paraffin and acyl cyanide acylation reagents. Oxalyl chloride is a very effective acylating reagent, can be widely used in the preparation of acyl azide, bromine rubber, carbon amide, adjacent second quinoline, azo ketones, lactones, and realize cycloaddition of ketene, intramolecular Fridel - Crafts acylation reaction. Similar to those of thionyl chloride and oxalyl chloride with the acid effect will give gas by-products, generation of chloride can be easily separated.
