CAS. 497-18-7

The carbohydrazide is the most advanced boiler water oxygen scavenger in the world today. It features low toxicity and high melting point. Its deoxidation efficiency is far greater than common materials. It is ideal for safety and environmental protection.

The user can either put it directly into water or use its aqueous solution as an antioxidant for boilers. For 1mol O2, the dosage of carbohydrazide should be 0.5mol or more. The temperature range should be 87.8-176.7 ℃. It should be used after thermal deaeration.
