Isobutylene – C4H8

This page contains basic information about isobutylene or “isobutylene, 2-methylpropene” (C4H8), such as its physical properties, health effects, means of detection (C4H8 gas detector) and adapted respiratory protection equipment (gas mask or driven air purifier type AX with gas filter). collects.

Basic properties of toluene (C4H8)

isobutylene (C4H8), a branched compound with four carbon atoms It is an alkene and is colorless at normal temperature and pressure. It is a flammable gas. The main method of industrial production remains the catalytic dehydrogenation of isobutane7. Production of isobutene, a gasoline additive that increases the octane rating to MTBE (methyl tert-butyl ether) increased significantly in the 1990s as demand increased.

Health effects of isobutylene (C4H8)

Isobutene is an extremely flammable gas. It carries the risk of explosion. Usually stored as compressed gas, in addition to explosions, there is a risk of creating a suffocating atmosphere if released uncontrollably by simple oxygen depletion. 

Isobutylene detector (C4H8)

The concentrations of this colorless and odorless gas are only C4H8 gas detector can measure accurately. Although explosive at 1.8 vol%, measuring explosiveness with this toxic gas is useless, so ppm isobutylene detection we will use .

Isobutylene calibration gas cylinders are available for the calibration and gas testing of your fixed or portable gas detectors.

C4H8 respiratory protection (Isobutylene)

With AX type anti-gas filter for short-term work half mask or full face masks filtered respiratory protection devices, such as more comfortable ones for long-term and demanding work.  powered air purifying respirator should be used
