Description
Technical field:
The utility model relates to a kind of equipment that removes catalyzer in the high-activity polyisobutene reactant.
Background technology:
What the present invention discussed is to produce in the high-activity polyisobutene process, and iso-butylene carries out low temperature cationic polymerization under the effect of boron series catalysts, after reaching desired molecule amount and transformation efficiency, should stop immediately polyreaction.Mostly adopt at present the aqueous solution of water, alcohol, acetonitrile, ammonia or mineral alkali to stop polyreaction.
Adopt the organism class as reaction terminating agent, its advantage is can be miscible fast with organic phase, but weak point is lower with the affinity of boron series catalysts, causes catalyst deactivation slow, while is water extracting and separating catalyst deactivation product complicated subsequently, and desired result is not good.
Adopt water as the terminator of reaction, its advantage is both to have made the catalyst deactivation simultaneously can also be as the extraction agent of catalyst deactivation product.But its shortcoming is bad with the miscible effect of reaction organic phase, catalyst deactivation is incomplete, the molecular weight distribution of reaction product is broadened and isomerization, the boron series catalysts of inactivation still remains in the reactant with acid state simultaneously, not only affect quality product, also the subsequent technique process is produced stronger corrosive nature.
Adopt the aqueous solution of ammonia or mineral alkali as the terminator of reaction, owing to can carry out neutralization reaction with an acidic catalyst, the termination effect is better, but neutralization reaction can form in a large number not diffluent salts substances, causes detersive efficiency decline and filtration difficulty and often causes the problems such as equipment, pipeline obstruction.
The utility model content
The purpose of this utility model provides a kind of equipment that removes catalyzer in the high-activity polyisobutene reactant.Solve in the past common simple three washing process products catalyst residue many, or adding alkaline reagents catalyst neutralisation forms a large amount of salts substances in for the first time washing, causes the blockage problem of detersive efficiency decline and filtration difficulty and frequent handling equipment, pipeline.
The equipment that removes catalyzer in the high-activity polyisobutene reactant described in the utility model comprises three mixing tanks, three water-and-oil separators and pipeline; The entrance of mixed once device is connected with isobutene polymerisation reactant supplied materials pipe, the outlet of mixed once device is connected with the entrance of a water-and-oil separator, the water outlet of a water-and-oil separator is connected with wastewater discharge pipe, the organic phase outlet of a water-and-oil separator is connected with the entrance of secondary mixer, the entrance of secondary mixer simultaneously with contain the fresh water pipe of alkaline reagents and be connected, the outlet of secondary mixer is connected with the entrance of secondary oil water separator, the water outlet of secondary oil water separator is connected with wastewater discharge pipe, the organic phase outlet of secondary oil water separator is connected with three mixer entrances, three times mixer outlet is connected with No. three water-and-oil separator entrances, No. three water-and-oil separator water outlets are connected by the entrance of cycling use of water pipe with the mixed once device, No. three water-and-oil separator organic phase outlets are connected with after-treatment system, and fresh water pipe is connected with the entrance of No. three mixing tanks.
With a washing water (from the water after three washings) and the isobutene polymerisation reactant mixed once device that contains solvent, through the mixing tank Forced Mixing, stop polyreaction and the most of catalyzer of hydrolysis removal, the mixed solution static layering is divided into organic phase and water, wherein water is drained, and organic phase enters secondary mixer;
The fresh water that is added with alkaline neutralization reagent enters secondary mixer with the organic phase of separating, through the mixing tank Forced Mixing, in the washing and organic phase in remainder catalyst, the mixed solution static layering is divided into organic phase and water, wherein water is drained, and organic phase enters mixing tank No. three times;
