If you want to know the boiling point of simethicone, you must first understand what silicone oil is. Silicone oil usually refers to a linear polysiloxane product that maintains a liquid state at room temperature. It is generally divided into two types: methyl silicone oil and modified silicone oil. The more 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, and good hydrophobicity.

Silicone oil is obtained by hydrolysis of dimethyl dichlorosilane with water to obtain the initial polycondensation ring body. Silicone oil can be obtained by removing low boilers from a mixture of different polymerization degrees by vacuum distillation.

The boiling point of simethicone

According to HG/T 2366-1992 "Simethicone Oil", there are multiple specifications of simethicone oil, and different specifications have different flash points, such as 201-10, whose flash point is required to be greater than 150 °C; 201-100 and above Specifications, flash point are required to be greater than 290 ℃. There is no boiling point of simethicone in the standard, but the flash point of specifications above 201-100 is greater than 290°C, so its boiling point is much greater than 300°C.
