What is the melting point of urea fertilizer?
What is the melting point of urea fertilizer?
Urea has important uses as a fertilizer and feed supplement, as well as a starting material for the manufacture of plastics and drugs. It is a colourless, crystalline substance that melts at 132.7° C (271° F) and decomposes before boiling.

Why does urea have a high melting point?
Why is urea’s melting point so much higher than naphthalene’s? Urea is capable of hydrogen bonding, so the intermolecular forces in solid urea are much stronger than the forces in solid naphthalene.
What happens when urea is heated?
On heating two molecules of urea at I 50∘C, a white solid biuret is formed with the evolution of ammonia.
How do you determine the melting point of urea?
Crush the urea to a powder. Load the powder into a capillary tube as before. o Attach the capillary to the thermometer with the rubber band. Heat the oil bath to 110°C, which is about 20° below the reported melting point of 132°C for urea.
How is the melting point of benzoic acid determined?
The melting point of benzoic acid is 122.4 degree Celsius. Determining the melting point of benzoic acid 1. To determine the melting point of benzoic acid, make sure the melting point device is close to room temperature before beginning a melting point analysis. 2. To determine the melting point of benzoic acid,…
How is benzoic acid harmful to the environment?
Benzoic acid appears as a white crystalline solid. Slightly soluble in water. The primary hazard is the potential for environmental damage if released. Immediate steps should be taken to limit spread to the environment. Used to make other chemicals, as a food preservative, and for other uses.
What is the role of benzoic acid in food?
It has a role as an antimicrobial food preservative, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, an EC 1.13.11.33 ( arachidonate 15-lipoxygenase) inhibitor, a plant metabolite, a human xenobiotic metabolite, an algal metabolite and a drug allergen. It is a conjugate acid of a benzoate.
How does phenylbutyrate and sodium benzoate affect the liver?
Both phenylbutyrate and sodium benzoate act by promoting an alternative pathway of nitrogen elimination. Neither phenylbutyrate nor sodium benzoate have been linked to cases of liver injury either in the form of serum enzyme elevations during therapy or clinically apparent acute liver injury.
