Isobutylene - C4H8

Isobutylene - C4H8

This page brings together the main information on isobutylene or "isobutene, 2-methylpropene" (C4H8) such as its physical characteristics, its effects on health, the means of detecting it (C4H8 gas detector) as well as the appropriate respiratory protection equipment (gas mask or assisted ventilation device with gas filter type AX).

Main characteristics of toluene (C4H8)

Isobutylene (C4H8) is a branched alkene with four carbon atoms that is a colorless, flammable gas at standard temperature and pressure. The main method of industrial production remains the catalytic dehydrogenation of isobutane. 7 Isobutene production increased sharply in the 1990s with the increasing demand for MTBE (methyl tert-butyl ether), a gasoline additive that increases its octane rating.

Health effects of isobutylene (C4H8)

Isobutene is a highly flammable gas. It presents an explosion hazard. It is generally stored as a compressed gas, the risk being, in addition to explosions, that it will produce an asphyxiating atmosphere if released in an uncontrolled manner simply by depletion of oxygen.

C4H8 (Isobutylene) gas detector

Colorless and odorless, only a C4H8 gas detector can accurately measure the concentrations of this gas. Although explosive at 1.8% volume, an explosiveness measurement is useless with this toxic gas, so we will move towards detecting isobutylene in ppm.

For the calibration and gas testing of your fixed or portable gas detectors, isobutylene standard gas cylinders are available.

Isobutylene (C4H8) respiratory protection

We will move towards filtering respiratory protection such as a half-mask or a full mask with an AX-type anti-gas filter for short-term interventions or towards a powered ventilation device (more comfortable) for long and strenuous work.
