purpose

It is used as stable and non-toxic food aerosol sprayer and medium gas.

Impact on the environment

Health hazards

Invasion route: inhalation.

Health hazards: at present, there is no report of occupational poisoning, but pyrolysis can release highly toxic f-smoke.

Toxicological data and environmental behavior

1. Acute toxicity: rats inhaled 80% of the product for 4 hours, and no abnormality was found (20% was O2).

2. Hazard characteristics: in case of high heat, the internal pressure of the container will increase, and there is a risk of cracking and explosion.

Combustion (decomposition) product: hydrogen fluoride.

3. Laboratory monitoring method:

Gas chromatography method for determination of harmful substances in air (Second Edition), edited by hangshiping.

Properties

Octafluorocyclobutane has been widely used in high-voltage insulation, cleaning and etching, plasma treatment and other technical fields in recent years because of its stable properties, non-toxic, zero ozone depletion potential (ODP) and good insulation. It is mainly used to prepare mixed refrigerant instead of CFC-12, and can be used as stable and non-toxic drug aerosol ejector
