Silicone oil usually refers to linear polysiloxane products that remain liquid at room temperature.  Generally divided into methyl silicone oil and modified silicone oil two categories.  The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, its organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, good hydrophobic performance.  It is made of dimethyldichlorosilane and water hydrolysis to obtain the initial condensation ring, ring by cracking, rectification to produce a low ring, and then the ring, the head agent, the catalyst put together to get a mixture of different polymerization degrees can be obtained, by vacuum distillation to remove the low boiling matter can be prepared silicone oil.

Silicone oil is a commonly used chemical material, widely used in lubrication, sealing, insulation, surface treatment and other fields.  The following will introduce the production process of silicone oil in detail. 

The main raw materials of silicone oil include silica, gasified xenon, organic solvent and so on.  Before production, it is necessary to ensure the quality and purity of these raw materials to ensure the quality of the final product.  The raw material preparation stage also needs to test, weigh, mix and other operations on the raw material.

Hydrolysis reaction

The hydrolysis reaction is a key step in the production of silicone oil, in which silica reacts with gasified xenon at the right temperature and pressure to produce silanol.  Hydrolysis reaction is an exothermic reaction, and the reaction conditions need to be strictly controlled to prevent the occurrence of side reactions

Acetation reaction

Esterification is a key step in the conversion of silicon into silicone oil, in which silanol reacts with organic acids or organic acid esters to produce silicone oil.  The esterification reaction usually requires a certain time and temperature to ensure that the reaction is completely carried out.

Distillation and purification

Refining is to remove impurities and unreactants in silicone oil, improve the purity of silicone oil, in this step, through heating and condensation, the silicone oil and impurities are separated to obtain pure silicone oil.
