Abstract
The present invention relates to methods of preparing purified cyclopropylene (1-methylcyclopropylene) gas employing one or more non-reactive purification processes to purify substances including, without limitation, cyclopropene (1-methylcyclopropylene) gas and/or lithio-cyclopropene.
Claims20
A method of preparing a purified cyclopropene gas, comprising:
- producing a treated lithium-based precursor of 1-methylcyclopropene gas by subjecting a lithium-based precursor of 1-methylcyclopropene gas to a vacuum distillation system to at least partially remove impurities and/or volatiles;
- reacting the treated lithium-based precursor of 1-methylcyclopropene gas with water to generate an unpurified 1-methylcyclopropene gas;
- and
- producing a purified 1-methylcyclopropene gas by scrubbing the unpurified 1-methylcyclopropene gas with at least one non-reactive scrubber, wherein the non-reactive scrubber is a polar or non-polar compound, and at least partially removes synthesis and/or reaction contaminants from the generated unpurified 1-methylcyclopropene gas,
- wherein the purified 1-methylcyclopropene gas has regulatory compliance impurity presence of less than 0.1 wt. % for each of the synthesis and/or reaction contaminants.

A method of preparing a purified cyclopropene gas, comprising:
- synthesizing a purified 1-methylcyclopropene gas by reacting a treated lithium-based precursor of 1-methylcyclopropene gas with water to generate an unpurified 1-methylcyclopropene gas, wherein the treated lithium-based precursor is generated by subjecting a lithium-based precursor of 1-methylcyclopropene gas to a vacuum distillation system to at least partially remove impurities and/or volatiles, and scrubbing the unpurified 1-methylcyclopropene gas with at least one non-reactive scrubber, wherein the non-reactive scrubber is a polar or non-polar compound, and at least partially removes at least one synthesis and/or reaction contaminants from the generated unpurified 1-methylcyclopropene gas,
- wherein the purified 1-methylcyclopropene gas has 1-chloro-2-methylpropene (1-CMP) and 3-chloro-2-methylpropene (3-CMP) each present in an amount of less than 0.1 wt. %.
