Hydrocarbyl the cyclosiloxane preparation method (by machine translation)

The invention discloses a preparation method of alkyl cyclosiloxane. The preparation method is characterized by comprising the following steps: taking alkyl halogenosilane as a raw material, taking crown ether as a solvent and dropping the alkyl halogenosilane in a mixed solution formed by water and the crown ether while continuously stirring the alkyl halogenosilane; carrying out hydrolysis at a certain temperature to carry out condensation polymerization; standing after the reaction to carry out layering; and directly carrying out decompressed rectification on the obtained hydrolyzed oil to separate trialkylcyclotrisiloxane, tetraalkylcyclotetrasiloxane, pentaalkylcyclopentasiloxane and hexaalkylcyclohexasiloxane. The preparation method has the advantages that alcohols and low-boiling point hydrocarbons are not used as solvents, the crown ether is used as solvent and direct rectification is carried out on the prepared hydrolyzed oil to obtain the alkyl cyclosiloxane, so that the processes of washing, neutralization, drying and filtering are saved; and the solvent which undergoes standing and layering after the hydrolysis can be reused or can be cooled to a certain temperature to separate out the crown ether for recovery, so that the production cost is saved.
