Abstract
PPS OH are important chemical products, are widely used in electroplating every trade industry.The present invention provides a kind of PPS OH production technologies.
Description
Technical field
The present invention relates to chemical production field, especially PPS-OH production fields.
Background technology
PPS-OH is important chemical products, is widely used in electroplating every trade industry.
The content of the invention
The present invention provides a kind of PPS-OH production technologies, production principle and technological process：By anhydrous sodium hydrogensulfite and water
With 3:7 mass ratio is separately added into enamel reactor, and compound concentration is 30% solution of sodium bisulfite.It is warmed up to 70-90
DEG C, regulation pH values are added dropwise epoxychloropropane 5.0 or so under pressure 0.5-0.7MPa, isolation air conditionses, drip within 4 hours
Add it is complete, while be added dropwise while stir, insulation 4 hours after cool, gradually there is white crystal to separate out, by centrifugation obtain partly
Finished product 1- chlorine-2-hydroxyl propane sulfonic acid sodium, centrifugate reuse continues to configure solution.It is dissolved in water semi-finished product to retort, control
Temperature is stirred at 60 DEG C to pyridine is added dropwise in reaction vessel, and with the reaction of 1- chlorine-2-hydroxyl propane sulfonic acids sodium, insulation is entered for 20 hours
Row salt-forming reaction, after completion of the reaction, is distilled, mainly remove the complete pyridine of unreacted, condense reclaim pyridine and
The water being distilled off simultaneously can be arranged with reuse outside fixed gas.Distillation substrate adds water and is configured to certain density solution and obtains final product product
Product.Main component is PPS-OH, and submember is NaCl.
Brief description of the drawings：
Fig. 1 is addition reaction equation；Fig. 2 is salt-forming reaction equation.
Claims (2)
1. the present invention provides a kind of PPS-OH production technologies.
