The trimethoxy hydrogen silicon alcoholysis esterification pre-reaction device has the characteristics of high yield and continuous production, and has the advantages of increasing the product conversion rate, improving the product content and increasing the economic benefit by reducing the production cost.
Description
Technical field
The utility model relates to a kind of trimethoxy hydrogen silanol and separates esterification pre-reaction device.
Background technology
In the organosilicon industry, silane coupling agent is one type of silane with organo-functional group, mainly is widely used in the industries such as tackifier of surface treatment, Inorganic Fillers Filled plastics and sealing agent, caking agent and the coating of spun glass.Wherein Trimethoxy silane is one type of application utmost point coupling agent widely; The supply of reactant HSICL3 and CH30H can not realize etc. that mole number matees requirement in tradition worker's trichlorosilane and the method that Trimethoxy silane is produced in the methyl alcohol alcoholysis; Come the control volume ratio with existing measurement means, its precision is too low; Mixture homogeneity and touch opportunity are all insufficient between the two in esterifying kettle, make main reaction insufficient, and the side reaction probability increases; Whole process of preparation is discontinuous, and step of esterification is separated with the fractionation by distillation step; And product yield is low, generally has only about 50% purity less than 98%.
The utility model content
Its purpose of the utility model just is to provide a kind of trimethoxy hydrogen silanol to separate esterification pre-reaction device, the characteristics that have the yield height, can be continuously produced, and improved the transformation efficiency of product, improved product content, with the increase economic benefit that reduces production costs.
The technical scheme that realizes above-mentioned purpose and take; Comprise esterifying kettle and esterification column; Said esterifying kettle and esterification column top connect the pre-reaction jar; The pre-reaction pot bottom connects catalyzer pipeline and trichlorosilane pipeline and under meter, and pre-reaction jar upper end connects methyl alcohol pipeline and under meter, and the esterifying kettle in said esterifying kettle and the esterification column connects the methanol gas pipeline.
Compared with prior art the utlity model has following advantage.
1. this device is that trichlorosilane and these two kinds of raw materials of methyl alcohol are mixed and add catalyzer formation compound; React under the effect of catalyzer along with temperature controlling makes its compound the back in being added drop-wise to esterification column; The methanol gas of controlling suitable proportion simultaneously gets into the esterifying kettle esterification column; Guarantee the abundant reaction of its compound and excessive response does not take place, guarantee that its feed stock conversion can reach 99.0%;
2. the product of producing through this device, content reach more than 99%, and pH value is 5-6, can satisfy the production needs of derived product.This technology has been save neutralization, rectification process, saves production cost, save energy etc.;
3. this device is a Sequential Production, once carries out the reacted pattern of an esterifying kettle with traditional technology and compares, and can improve the production production capacity, practices thrift human cost, enhances productivity.

[0011]Embodiment
(1) methyl alcohol and these two kinds of raw materials of trichlorosilane are passed through trichlorosilane pipeline and under meter 5; Methyl alcohol pipeline and under meter 6 are delivered to pre-reaction jar 3; The input of two kinds of raw materials of spinner-type flowmeter control is installed in the pipeline, observes pre-reaction jar 3 temperature, if temperature of reaction is lower than or exceeds-4 ℃ to 4 ℃ normal range; Should in time adjust the ratio of two kinds of raw material feed rate ratio control, make pre-reaction jar 3 interior temperature be controlled at-4 ℃ in 4 ℃ normal range in 2:1 (volume ratio);
(2) after pre-reaction jar temperature is controlled at normal range, carry out the interpolation of catalyzer, can fully react after making the compound that is reflected at pre-reaction jar 3 of trichlorosilane and methyl alcohol be added drop-wise in the esterification column 2 through catalyzer pipeline 4;
(3) have methanol gas to pass through methanol gas pipeline 1 in addition and get into the esterification column from esterifying kettle 2, it is consistent with the rate of addition of pre-reaction jar 3 that the flow of unit methanol gas keeps;
(4) unreacted in the compound in the pre-reaction jar 3 completely the methanol gas in compound and the esterifying kettle 2 carry out secondary response again, guaranteed the abundant reaction of raw material, stopped the excessive response of raw material.
Claims (1)
1. a trimethoxy hydrogen silanol is separated esterification pre-reaction device; Comprise esterifying kettle and esterification column (2); It is characterized in that said esterifying kettle and esterification column (2) top connects pre-reaction jar (3), pre-reaction jar (3) bottom connects catalyzer pipeline (4) and trichlorosilane pipeline and under meter (5); Pre-reaction jar (3) upper end connects methyl alcohol pipeline and under meter (6), and the esterifying kettle in said esterifying kettle and the esterification column (2) connects methanol gas pipeline (1).
