| Exposure to 1,3-butadiene resulting from the use of products containing isobutane as a propellant is expected to be low. |
|
| Butane and isobutane will be assessed separately as part of the Government's medium priorities. |
|
| Alkylation produces high octane gasolines from isobutane and butene, which are gassy molecules containing 4 carbon atoms. |
|
| However, there are two different butanes, C4H10, and these two molecules, called butane and isobutane, are constitutional isomers. |
|
| The end result is the addition of isobutane to isobutylene to form isooctane, the molecule that is the basis of octane ratings seen at the gas pumps. |
|
| Isobutane also contains very low amounts of 1,3-butadiene, which is produced during the refining of isobutane. |
|
| Alongside it lies the heat exchanger, a system of interlaced cylinders and tubes in which the geothermal water and isobutane circulate. |
|
| Several explosions have been reported in refrigerators using isobutane as a result of the gas leaking into the electrical system. |
|
| The lines have 90-mm single-screw extruders with three pump heads for isobutane blowing agent and 120-mm cooling extruders. |
|
| Alkylation combines light olefins and isobutane, thus providing refiners an opportunity to increase their crude barrel value. |
|
| It consists predominantly of butane, isobutane and butadiene. |
|
| The Government of Canada will examine the existing risk management activities so that they are appropriate and take into account any new information regarding exposure to 1,3-butadiene in isobutane. |
|
| Because Canadians' exposure to 1,3-butadiene in isobutane is low, the Government of Canada is not currently recommending specific actions to reduce Canadians' exposure. |
|
| Based on the most recent data available, isobutane containing very low amounts of 1,3-butadiene is manufactured in Canada and imported into Canada. |
|
| The Government of Canada has conducted a science-based evaluation of 1,3-butadiene in products containing isobutane as a propellant, called a screening assessment. |
|
| The C4 Oleflex process uses catalytic dehydrogenation to convert isobutane to isobutylene. |
|
| An improved correlation of the viscosity of isobutane has been published. |
|
| The solubilities of butane and isobutane in PP are shown in Figs. |
