Abstract
The present invention relates to the field of chemical industry product production, particularly to the field of trimethylamine hydrochloride production, wherein the trimethylamine hydrochloride is an important chemical industry product, and the trimethylamine hydrochloride production is an intermittent production process, and mainly comprises synthesis, concentration, purification, drying, and the like.
Description
Technical field
The present invention relates to chemical products production field, especially trimethylamine hydrochloride production field.
Background technology
Trimethylamine hydrochloride is a kind of important chemical products.Trimethylamine hydrochloride process units is batch production stream
Journey, mainly includes synthesis, concentration, purification, dry etc..
The content of the invention
Technological process
Process units is batch production flow process, and the hydrochloric acid produced by the device for absorbing tail gas for measuring is added in synthesis reactor,
Front three amine gas are passed through, 50 DEG C of controlling reaction temperature, response time are 6 hours, after the completion of reaction by the way of vacuum distillation
Product is concentrated, enriched product controls vapo(u)rizing temperature for 100 DEG C or so, and distillation pressure -0.9Mpa, distillation time are 10
h.Enter after the condensed device condensation of water vapour that distillation is produced kettle recovery is received to other operations.Uncooled vacuum pump is produced
Raw organic exhaust gas enter the process of tail gas of vacuum gas pump absorption system.The enriched product that distillation is produced is cooled to 20 DEG C, is centrifuged, generation
Waste water enters Sewage Disposal process.Jing microwave dryers are dried centrifugation product again, and drying time is 10h.Obtain trimethylamine
Hydrochlorate.Vacuum pump used by rake type drier be WLW type vertical oilless vacuum pump units, vacuum pump produce waste gas Jing vacuum
The process of pump tail gas absorbing system.
Reaction equation：
Salt-forming reaction
。
