 Core Features

1. High chemical activity: The carbon carbon triple bond contained in Propyne molecules is a typical unsaturated bond, which is prone to addition, polymerization, oxidation and other reactions, and is a key intermediate for the synthesis of various fine chemicals.

2. Excellent combustion performance: During the combustion of Propyne, the flame temperature is high, the heat release is concentrated, and the combustion products are mainly carbon dioxide and water, which are relatively clean.

3. Easy liquefaction storage and transportation: Propane has a low critical temperature and pressure, and can be converted into a liquid state by moderate pressure at room temperature, which is convenient for storage and transportation and improves usability.

4. Strong purity controllability: Advanced processes such as distillation purification are used for Propyne, which can accurately control product purity, reduce the interference of impurities on subsequent reactions, and ensure product quality stability.

 Main application areas

1. In the field of chemical synthesis, Propyne is used as a core intermediate for the synthesis of important chemical raw materials such as acetone, acetaldehyde, acrylic acid, methyl methacrylate, etc; At the same time, Propyne can be used to prepare fine chemicals such as alkyne alcohols and alkyne derivatives, which are widely used in industries such as coatings, adhesives, plastics, and pharmaceuticals.

2. In the field of material preparation, Propyne can be used as a polymerization monomer or copolymer monomer to participate in the synthesis of high-performance polymer materials, such as new resins, rubber, etc., to enhance the material's high temperature resistance, aging resistance, and other properties; Propyne can also be used to prepare carbon material precursors.

3. In the field of energy and welding, Propyne can be used as a high-temperature flame fuel due to its high combustion temperature, and is used for metal cutting, welding, and other operations; Propyne can also be used as a fuel additive to improve the combustion efficiency of fuel.

4. Research and experimental fields: Propyne, as a basic organic chemical reagent, is used in various organic synthesis reaction mechanism research, new catalyst performance testing and other scientific research experiments. It is a commonly used reagent in universities, research institutes and chemical research and development enterprises.

5. Other fields: Propyne can be used to prepare special gas mixtures and applied in processes such as vapor deposition in the electronics industry; It can also be used as an intermediate raw material for refrigerants.

 Safety and Storage Instructions

1. Safety Warning

Propyne is a highly flammable gas that can form explosive mixtures when mixed with air. It is highly flammable and explosive when exposed to open flames and high heat; Its vapor is heavier than air and can spread to a considerable distance at lower levels. It will ignite and reignite when exposed to a source of fire. Strict adherence to explosion and fire prevention regulations is required during operation, and it is strictly prohibited to use in non-smoking and fire-resistant areas. Necessary fire-fighting equipment (such as dry powder fire extinguishers and carbon dioxide fire extinguishers) should be equipped.

Inhaling high concentrations of Propyne may cause discomfort such as dizziness, headache, nausea, vomiting, etc. During operation, it is necessary to wear protective masks and goggles that meet the standards to ensure good ventilation in the operating environment.

2. Storage requirements

Propyne steel cylinder should be stored in a cool and ventilated warehouse, away from sources of fire and heat, and the temperature should not exceed 30 ℃; Propyne steel cylinders should be stored separately from hazardous chemicals such as oxidants, halogens, and strong acids, and mixed storage and transportation should be avoided.

Using pressure resistant steel cylinder packaging, the steel cylinder should undergo regular pressure resistance testing; During storage and transportation, it is necessary to handle with care to prevent collisions, exposure to sunlight, and heat from the steel cylinders. Valves should be sealed and protected to prevent gas leakage.
