Description
Technical field
The utility model relates to a kind of chemical production equipment, relates in particular to the system that a kind of hydrolyzing methyl trichlorosilane is produced methyl siliconic acid.
Background technology
It is main chain with the Si-O key that organosilicon material mainly is one type, on Si, introduces the macromolecular compound of organic group as side chain again, and its excellent performance, function uniqueness are widely used in fields such as military project, space flight, medical treatment, chemical industry.Produce (CH in " direct method "
3)
2SiCl
2Process in, produce the METHYL TRICHLORO SILANE of 8～15wt% approximately, this by product boiling point is 66 ℃, on producing, separates obtaining through rectifying tower.
Along with the scale of China's methyl chlorosilane monomer production constantly enlarges, the absolute quantity of METHYL TRICHLORO SILANE also increases rapidly.Because consumptions such as the domestic derived product silicone resin that can utilize METHYL TRICHLORO SILANE preparation, silane coupling agent are little; And METHYL TRICHLORO SILANE to belong to hazardous chemical again not easy to store; Various reasons causes METHYL TRICHLORO SILANE, and seriously drug on the market; Make METHYL TRICHLORO SILANE become the sub product of the headache of an organosilane monomer manufacturing enterprise; Its price also falls to the processing costs of 500 yuan/ton of present subsidy downstream processing enterprises from 10000 yuan/ton a tunnel of beginning of the century, cause serious burden for organosilicon enterprise.
METHYL TRICHLORO SILANE concentrated acid hydrolysis process can be converted into HCl gas and methyl siliconic acid with METHYL TRICHLORO SILANE.HCl gas can use as raw material for the methyl chloride synthesizer of an organosilane monomer manufacturing enterprise, reduces material cost, reaches the recycling economy purpose; Methyl siliconic acid also can be used for preparing the methyl siliconic acid salt water-repellent.
Discontinuous method is adopted in present METHYL TRICHLORO SILANE hydrolysis more, and the METHYL TRICHLORO SILANE transformation efficiency is not high, severe operational environment, and energy consumption is big, and can not continuous discharging slag.
