Description
Technical field
The invention belongs to chemical industry to purify technical field of tools, specifically a kind of environment-friendly type toluene distillation kettle.
Background technique
Toluene is largely used as solvent and high-knock rating gasoline additive and the important source material of organic chemical industry, and toluene is derivative
A series of intermediates, be widely used in the production of the fine chemicals such as dyestuff, medicine, pesticide, explosive wastewater, auxiliary agent, fragrance, also use
In synthetic material industry.Toluene carries out a benzyl chloride, benzyl dichloride and three benzyl chlorides that pendant chlorine obtains, including their derivative benzene
Methanol, benzaldehyde and chlorobenzoyl chloride (generally also obtaining from benzoic acid phosgenation) are closed in medicine, pesticide, dyestuff, especially fragrance
It is widely used in.The ring chlorizate of toluene is the intermediate of pesticide, medicine and dyestuff.Toluene oxidation obtains benzoic acid, is
Important food preservative (mainly using its sodium salt), also serves as the intermediate of organic synthesis.Toluene and benzene derivative are sulfonated
Intermediate obtained, including p-methyl benzenesulfonic acid and its sodium salt, CLT acid, Toluene-2,4-diisocyanate, 4- disulfonic acid, benzaldehyde -2,4- disulfonic acid and
Toluene sulfochloride etc., the production for detergent additives, chemical fertilizer anti-caking additive, organic pigment, medicine and dyestuff.Toluene
A large amount of intermediate is made in nitrification.Can derive to obtain many final products, wherein polyurethane product, dyestuff and organic pigment,
Rubber chemicals, medicine, explosive etc. are mostly important.
It is higher to toluene purity requirement just because of the purposes of toluene is as extensive, thus frequently with distillation still to toluene into
Row purification.Distillation still used at present is mostly iron or glass material in the prior art, iron distillation still good heat conduction effect, but
It is the situation for being inconvenient to observe in distillation still；The distillation still of glass material facilitates observation, but heat-conducting effect is general, and in height
It is easy to happen danger under temperature, not can be carried out large batch of distillation operation；In addition, the structure of existing distillation still is single, cost compared with
It is low, but only have the function of heating distillation, in process of production, needing to absorb amount of heat just can be carried out distillation procedure, be easy
It results in waste of resources, is unfavorable for environmental protection；Also, a large amount of residues can be left on the inner wall of distillation still after distilling, need to spend
Expense manpower and material resources are cleared up, if cleaning will affect the effect of distillation next time not in time.
Summary of the invention
In order to make up for the deficiencies of the prior art, it solves the problems, such as, a kind of environment-friendly type toluene distillation kettle proposed by the present invention.This
