Introduction

Carbohydrazide, also known as carbohydrazide, is a high-performance oxygen scavenger that can be used in all types of boilers. Carbohydrazide is a white water-soluble solid that decomposes at a melting point of about 153°C.

Carbohydrazide can be used as an oxygen scrubber to directly replace hydrazine in any boiler without related safety hazards and preventive measures. The product is based on volatile chemicals, so it does not leave dissolved solids and minimal ammonia in the boiler system. It does provide excellent oxygen corrosion protection as well as excellent feedwater and boiler system passivation. Carbohydrazide reacts directly with oxygen. It helps prevent oxygen damage and continues to passivate the metal surface during wet layup. Carbohydrazide can also be used as a curing agent for epoxy resins.

Carbohydrazide is obtained by crystallization from aqueous ethanol. It decomposes when melted and is easily soluble in water. The aqueous solution is alkaline, hardly soluble in ethanol, and insoluble in alcohol, ether, chloroform and benzene.

Usage

It is widely used in the production of medicines, herbicides, plant growth regulators, dyes, etc.

(1) Carbohydrazide is a derivative of hydrazine and has strong reducing properties. Not only can be used as an intermediate for the production of energetic materials, but also can be directly used as a component of explosives and propellants

(2) It can be used as a preservative for oil refining equipment, and as a deoxidizer for boiler water treatment agent

(3) In the chemical fiber field, it can be used as a crosslinking agent for elastic fibers.

(4) It can be used as chemical raw materials and chemical intermediates, widely used in medicine, herbicides, plant growth regulators, dyes and other industries

It can be used as a component of rocket propellant, a stabilizer for color development and soap, an antioxidant for rubber, a deoxidizer for boiler water, and a passivator for metals.

Carbohydrazide is a derivative of hydrazine and has strong reducing properties. It can be used as an intermediate for the production of energetic materials, and it can also be directly used for the production of explosives and rocket propellants. It can also be used as a deoxidizer for boiler water and is the most advanced boiler water deoxidizer in the world today. It has low toxicity, high melting point and much higher deoxidation efficiency than currently used materials. It is an ideal product for safety and environmental protection.

Advantages

From the late 1970s to the early 1980s, developed countries such as Europe and the United States, Japan and other developed countries have invested a lot of research on new chemical oxygen scavengers, successively developed and applied a large number of new chemical oxygen scavengers to replace hydrazine and sodium sulfite, and applied them in industry. The main products are Carbohydrazide, dimethyl ketoxime, and acetaldoxime and have gradually been successfully promoted and applied in the chemical deoxidation of large and medium-sized thermal power generating units and various steam hot water boilers, effectively preventing boilers, etc. The corrosion of thermal equipment during operation and shutdown protection has achieved good economic and social benefits.

Carbohydrazide is mainly exported as a boiler deoxidizer. We have been in business relations with many renowned company: Shurtan gas chemical complex, Metito, Suez water technology& solutions. It is used in some domestic steel plants and power plants. The price is higher. Dosage: The amount of Carbohydrazide required to remove one part of oxygen is about 0.5 times. Compared with other oxygen scavengers, the unit cost is almost the same. But with the advantages of environmental protection, safety and chemical stability.
