versusPhenylhydrazineThe reaction generated by the reaction is less common. Organic compounds containing aldehyde or phenol groups, such as formaldehyde, acetaldehyde, and glutaraldehyde, will condense carbonyl groups with aromatic hydrazine. The reaction of hydrazone formation is a common condensation reaction, not a specific reaction (essentially, it can be considered a dehydration reaction). The equation related to the reaction only requires you to write the corresponding aldehyde and phenylhydrazine, and then the reaction product is dehydrated and reaches equilibrium. As the molecular weight of the carbonyl group increases, the condensation reaction becomes difficult. For example, formaldehyde, acetaldehyde and phenylhydrazine are easy to condense. However, when changing to citric acid and phenylhydrazine, a small amount of acid (such as benzoic acid or p-toluenesulfonic acid) should be added as the proton catalytic phase. The writing is relatively brief, I hope it will help you. Common hydrazone compounds are the lead dithizone reagent used in hospitals and the benzophenone hydrazone used as UV active curing.
Tips for wholesale of phenylhydrazine manufacturers:
The use of phenylhydrazine in the production process must pay attention to the use of standards. Phenylhydrazine can cause hemolytic anemia, methemoglobinemia, hyperbilirubinemia, and damage to the central nervous system, liver, kidney, and heart.
1. Acute poisoning: mild poisoning includes headache, dizziness, weakness, loss of appetite, abdominal pain, diarrhea, etc. Heavier fashion has difficulty breathing, convulsions, tremors, and even ataxia and unconsciousness. Cyanosis, jaundice, leukopenia, hemolytic anemia, hyperbilirubinemia, and liver and kidney damage may occur in severe patients.
2. Chronic poisoning: Heart, liver, and kidney damage can occur after long-term exposure. It can cause skin damage. In severe cases, blisters and edema can occur.
