Robenidine HCL - Reference Information
| use | as an antibacterial agent, it is effective against staphylococcus, hemolytic streptococcus, etc. Mainly used to treat avian cholera, avian typhoid fever, chicken autumn worm disease, etc. chlorobenzidine is a low-toxic and efficient anticoccidial drug, which can be used in chicken feed with a small dosage of 30-36g/t. it is forbidden during laying and the drug withdrawal period is 7 days. It can also be used in rabbit feed with a dosage of 50-66g/t. It is forbidden during pregnancy and the drug withdrawal period is 7 days. The new high-efficiency anti-coccidiosis drug has high curative effect, low toxicity and good palatability. It has good effects on acute or chronic chicken coccidiosis. Check the weight gain rate and feeding compensation of rabbits and poultry in the headquarters. This product is a variety of income from the the People's Republic of China Veterinary Pharmacopoeia (1990 edition, part 1). Anti-coccidiosis drugs have good effects on acute or chronic chicken coccidiosis. |
| production method | p-chlorobenzaldehyde is condensed with N,N'-diaminoguanidine hydrochloride. Preparation of N,N'-diaminoguanidine hydrochloride (1,3-Diaminoguanidine monohydrochloride,CH7N5 · HCl,[36062-19-8]): starting from sodium thiocyanate, thiosemicarbazide is prepared by addition and rearrangement with hydrazine hydrate. Then methylate dimethyl sulfate and hydrazinolysis were used to prepare N,N'-diaminoguanidine hydrochloride. Finally, calcium ammoniate was replaced with N,N'-diaminoguanide hydrochloride. Thiosemicarbazide is formed by the addition and rearrangement of sodium thiocyanate with water and hydrazine. Then methylate dimethyl sulfate and hydrazine to obtain N.N '-diaminoguanidine sulfate. Then replace calcium chloride with N.N '-diaminoguanidine hydrochloride. Finally, chlorobenzuanidine hydrochloride was prepared by condensation with p-chlorobenzaldehyde in reethanol with 94% yield. Sulfaamidine is used as raw material and is obtained by cyclizing with acetylacetone. Put sulfaamidine, acetylacetone, sodium bisulfite, sodium hydroxide and water into the reaction kettle, and heat and reflux for about 6 hours. When crystallization appears in the reaction solution, the reflux continues for 20h after adding acetylacetone. After recovering acetylacetone, add an appropriate amount of boiling water, filter while hot, and the filter cake is washed with hot water, recrystallized, and dried to obtain sulfamethazine. |
