Embodiment 1
[0066] Embodiment 1: Preparation of cyclopropene inclusion complex powder
[0067] The 1-MCP gas after the synthesis and purification is passed into 10 kilograms of absorption liquids that are composed of 14.5% α-cyclodextrin, 5% white carbon black and 80.5% water, and carry out inclusion absorption at normal temperature, and the stirring speed is 300 revolutions per minute, continue to feed 1-MCP gas for 3 hours, then quickly filter the absorption liquid mixture, rinse with absolute ethanol after the suction filtration, then suction filter, and finally dry at room temperature to obtain 1.9 kg containing 3.0 % 1-methylcyclopropene inclusion complex powder.
Embodiment 2
[0068] Embodiment 2: Preparation of cyclopropene inclusion complex powder
[0069] The synthesized and purified 1-MCP gas is passed into 10 kg of absorption liquid composed of 1% alkylated α-cyclodextrin, 49% white carbon black, and 50% water, and inclusion absorption is carried out at room temperature. The stirring speed is 300 rpm, and the 1-MCP gas is continuously fed for 5 hours, and then the absorption liquid mixture is subjected to rapid suction filtration. Kg contains 0.07% 1-methylcyclopropene inclusion complex powder.
Embodiment 3
[0070] Embodiment 3: Preparation of cyclopropene inclusion complex powder
[0071] The 1-MCP gas after the synthesis and purification is passed into 10 kg of absorption liquid composed of 49% esterified α-cyclodextrin, 0.1% white carbon black and 50.9% water, and carries out inclusion absorption at normal temperature, stirring The speed is 300 rpm, and the 1-MCP gas is continuously introduced for 2 hours, and then the absorption liquid mixture is subjected to rapid suction filtration. 3.2% 1-methylcyclopropene inclusion complex powder.
