3-Chloro-2-methylpropene Chemical Properties,Usage,Production

Description

3-Chloro-2-methylpropene is used as an intermediate to produce carbofuran, herbicides, plastics, pharmaceuticals and other organics. It is also used as an additive in textile and perfumes. It was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate and cationic polymerization of 3-Chloro-2-methylpropene with AICI3 and AIBr3 as initiators. It is also the reactant for the synthesis of cyclobutanone.

Uses

3-Chloro-2-methyl-1-propene was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate. It was used to study cationic polymerization of 3-Chloro-2-methyl-1-propene using using AICI₃ and A₃IBr, as initiators.

Definition

ChEBI: 3-Chloro-2-methylpropene is an organochlorine compound.

Biological Functions

MAC is a valuable index for clinical anesthesia, but it is seldom employed without taking other factors into consideration. For example, inhibiting movement in only 50% of patients is not acceptable. Consequently, if an inhalational agent were being used alone—that is, without the administration of other anesthetics or analgesic drugs—the anesthesiologist would employ a multiple of its MAC value to ensure immobility.MAC is frequently multiplied by a factor of 1.3 to achieve nearly 100% clinical efficacy. On the other hand, useful clinical results may be achieved with doses of anesthetics below MAC levels. For example, mild analgesia and amnesia often occur with doses of inhalational agents that are near 0.5 MAC. In this state, it may even be possible to communicate with patients intraoperatively, while their recall is limited.
