Trans dichloroethylene

Trans dichloroethyleneIt is an organic compound with the chemical formula C2H2Cl2. It is a colorless, slightly pungent, volatile liquid. Its melting point is about -49.4 º C, boiling point is about 47.7 º C, slightly soluble in water, and its density is about 1.2565. This substance is commonly used as an organic cleaning agent to replace HCFC-141B, such as 365AZ, which has the characteristics of no flash point, high cleaning power, and easy volatility.

application

Trans dichloroethyleneLow toxicity and active chemical properties, mainly used in industry as extractants for thermosensitive substances or solvents for certain polymer materials, as well as raw materials for organic synthesis. The application examples are as follows:

1. Prepare a low-temperature chamber effect environmentally friendly cleaning agent.

This environmentally friendly cleaning agent uses trans1, 2- TwoChloroethylene is the main component and the ultimate substitute for ozone depleting substances. It is also a solvent based azeotropic precision electronic cleaning agent that meets the low-temperature chamber effect and occupational disease prevention and control laws. It is a key technology product for clean production. This alternative application plan for environmentally friendly cleaning agents will attempt to meet the environmental policies of China as a developing country and the stricter regulations of developed countries, such as the EU's REACH standard, the US's ACGIH health requirements, Japan's air pollution regulations, etc., at the current technological stage, in order to meet the requirements of green suppliers.

Solved the flash point problem of using pure trans-1,2-dichloroethylene and can be directly applied to existing cleaning equipment; Solved the occupational disease prevention and control issues in the current use of ODS substitutes; Solved the replacement of greenhouse effect cleaning agents with high GWP; It can replace high cost cleaning agents and achieve the goal of reducing costs.

physical properties

Boiling point: about 48C

Density: Approximately 1.25 g/cm ³
