Description
Technical field
The utility model relates to a kind of pivaloyl chloride production equipment, especially relates to a kind of Special reverse for pivaloyl chloride production and answers flow container.
Background technology
Pivaloyl chloride is a kind of important acylating reagent; it has been widely used in the various medicine of synthesis and Pesticidal products; simultaneously it also can be used for synthetic polymer initator; in general; synthesis pivaloyl chloride needs isobutene and carbon monoxide to synthesize pivalic acid, and carries out chlorination reaction to it, generates chloro-pivalyl chloride; and then carry out rectifying generation finished product, above-mentioned operation needs special reaction flow container to adapt to above-mentioned reaction.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of Special reverse for pivaloyl chloride production and answers flow container, and the technical scheme of employing is as follows:
A kind of Special reverse for pivaloyl chloride production answers flow container, reaction flow container comprises the anti-corrosion layer of outer field heat-insulation layer and internal layer, the bottom of described reaction flow container is provided with jet chimney, steam inlet channel is provided with non-return valve, non-return valve top is provided with aeration sieve, described reaction flow container top is provided with methylpropanoic acid pipeline and phosphorus trichloride pipeline respectively, methylpropanoic acid pipeline and phosphorus trichloride conduit upper are provided with steam fog sieve, reactant liquor tank top is provided with blast pipe, blast pipe is connected with rectifying liquid pipe by magnetic valve, is also provided with electric heating sheets between described heat-insulation layer and anti-corrosion layer.
Further, described methylpropanoic acid pipeline and phosphorus trichloride pipeline are equipped with non-return valve.
Further, described heat-insulation layer adopts expanded polyethylene foam material, and described anti-corrosion layer adopts graphite material.
Further, described aeration sieve adopts glass fibre establishment.
The above-mentioned Special reverse for pivaloyl chloride production is adopted to answer flow container, vapours can be utilized to replace mixing plant, and there is heat due to steam itself, make heating liquid more even, accelerate the reaction time, the gas that blast pipe is discharged can be directly used in rectifying.
Accompanying drawing explanation
