Description

Methyl phenyl chlorosilane vapor-liquid hydrolysis reaction kettle

Technical Field

The utility model relates to the technical field of reaction kettles, in particular to a vapor-liquid hydrolysis reaction kettle for methyl phenyl chlorosilane.

Background

The operation steps of the hydrolysis reaction of the methyl phenyl chlorosilane are as follows: 1. dissolving methyl phenyl chlorosilane in a solvent, wherein the solvent is toluene or xylene; 2. placing a methyl phenyl chlorosilane solution into a reaction kettle; 3. water is continuously added into the reaction kettle to carry out hydrolysis reaction.

The water added in the process can only locally generate liquid-liquid hydrolysis reaction with the methyl phenyl chlorosilane, and the time consumed for completing the hydrolysis reaction is long, so that the production efficiency is low.

Therefore, how to overcome the above-mentioned drawbacks is a problem to be solved by the person skilled in the art.

Disclosure of Invention

In order to solve the technical problems in the background technology, the utility model discloses a methyl phenyl chlorosilane vapor-liquid hydrolysis reaction kettle.

The utility model provides a methyl phenyl chlorosilane vapor-liquid hydrolysis reaction kettle, which comprises a kettle body, wherein the kettle body is driven by a speed reducing motor to rotate clockwise and anticlockwise, so that methyl phenyl chlorosilane solution flows from the top to the bottom of the kettle body or flows from the bottom to the top; the kettle body is provided with a steam pipe for filling steam.

Firstly, enabling the kettle body to be arranged obliquely or vertically, and enabling methyl phenyl chlorosilane solution to enter from the lower end of the kettle body; then the gear motor drives the kettle body to rotate, the methyl phenyl chlorosilane solution slowly flows to the other end, and the methyl phenyl chlorosilane solution and water vapor carry out hydrolysis reaction while flowing; when the methyl phenyl chlorosilane solution flows to the other end completely, the hydrolysis is completed; the contact area is enlarged by the water vapor, and the water vapor automatically flows to the other end after the methyl phenyl chlorosilane is hydrolyzed, so that the hydrolysis is not hindered, the hydrolysis is more complete, and the reaction efficiency is higher.

The flow rate of the methyl phenyl chlorosilane solution is difficult to control, and the condition of too high flow rate can occur, so that the hydrolysis reaction is insufficient, and the problem is further improved and solved; the first baffle plate is provided with a notch; the steam pipe is arranged in the middle cavity. The arrangement of the notch enables the methyl phenyl chlorosilane to flow out of the notch only, reduces the flow area of the methyl phenyl chlorosilane solution, reduces the flow rate, and increases the flow time of the methyl phenyl chlorosilane solution at one time, thereby enabling the hydrolysis reaction to be more sufficient.

When the methyl phenyl chlorosilane solution flows from one end to the other end, there is a case that the flow is not sufficient, and based on this, it is further designed that: the notch is arranged at the bottom of the first baffle plate.

Because hydrolysis reaction can give off heat, set up the cooling chamber in the external wall of cauldron generally, cool with the cooling water, this kind of setting of cooling chamber, the structure is more complicated, and in this utility model, the heat concentrates in the bottom of the cauldron body, based on this, further design is: the kettle body is also internally provided with a second baffle plate which is axially arranged, and the first baffle plate is arranged at the upper end of the second baffle plate; the part of the lower end of the second partition plate forms a cooling cavity for filling cooling water.

The cooling water is cooled off the cauldron body from the mode of cooling chamber business turn over, and the effect is relatively poor, based on this, further design is: the cooling water pipes which are arranged in a snake shape are arranged on the lower end face of the second partition plate.

The traditional steam pipe has small outlet area and low reaction efficiency, so the problem is further improved and solved, and specifically, the lower end of the steam pipe is connected with a steam spraying pipe which is vertical to the kettle body, the lower end of the steam spraying pipe is provided with an axially arranged oblong steam spraying hole, and the two ends of the steam spraying hole are close to the end parts of the steam spraying pipe.
