Product Information

• Name: Isobutylene oxide
• Brand: Biosynth
• Description: Isobutylene oxide is an additive that is used as a fuel additive to reduce the formation of oxides of nitrogen (NOx) emissions. It consists of two parts, one being a glycol ether and the other being an epoxide. Isobutylene oxide reacts with isobutylene in the presence of oxygen to form an epoxide. This reaction requires activation energy, which can be provided by a catalyst such as platinum or palladium on alumina or silica gel. The hydroxyl group on the glycol ether provides nucleophilic attack on the epoxide, leading to cross-linking reactions and increased molecular weight. This reaction proceeds through three steps: hydrogen abstraction from isobutylene, proton transfer from the hydroxyl group, and deprotonation of the intermediate formed by proton transfer. In diesel engines, Isobutylene oxide reduces NOx emissions by increasing combustion efficiency and reducing diesel particulate matter emissions. Isobutylene oxide
