Description

The synthetic method of pyromellitic trimethylsilyl chloride
Technical field
The invention belongs to organic synthesis field, be specifically related to a kind of synthetic method of pyromellitic trimethylsilyl chloride.
Technical background
Pyromellitic trimethylsilyl chloride is a kind of important chemical feedstocks, main as producing various polyamide-based reverse osmosis membranes, thereby is applied to the aspects such as highly purified and gas delivery of sea water desaltination, water.Along with developing rapidly of polymer chemistry and materials chemistry, become gradually one of popular in the world research field.
Pyromellitic trimethylsilyl chloride adopts phosgene or triphosgene to react and produce with trimesic acid more at present.< < fine chemistry industry > > (08 phase in 2005) has reported one piece of < < Preparation of Trimesoyl Chloride from Trimesoyl Acid Using Triphosgene > >, this technique is introduced, triphosgene is solid Poison, and can also decompose and produce highly toxic product phosgene, hazardness is very large.< < fuel and chemical industry > > have reported the development > > of one piece of < < pyromellitic trimethylsilyl chloride in (in January, 1991), introduced with sulfur oxychloride and the synthetic pyromellitic trimethylsilyl chloride of trimesic acid, yield is 85~89%, purity after refining is higher, but its yield is on the low side.Also have data introduction to take trimesic acid as raw material, react preparation with phosphorus oxychloride (or phosphorus pentachloride), yield is 90%, but this method impurity is many and difficult separated, and yield is on the low side.
According to data introduction, Japan has developed with 1,3,5-trichlorobenzene as raw material, under uviolizing, 65 ℃, 98~490KPa condition, reacts generate pyromellitic trimethylsilyl chloride in sodium hydroxide, ethanol with cobalt-carbonyl, and its yield is 85.5%.The direct method of du pont company exploitation is under 200 ℃, 17MPa pressure, the reaction under nickelous chloride exists of sym-trimethylbenzene and sulfur oxychloride, resultant of reaction again with sulfurous gas effect, obtain pyromellitic trimethylsilyl chloride.Above technique relates to ultraviolet ray and High Temperature High Pressure, and high to processing unit requirement, energy consumption is high, and corresponding production cost is also high.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of synthetic method of pyromellitic trimethylsilyl chloride, whole procedure is to being safe from harm property of environment; Processing unit of the present invention is simple, energy consumption is little, cost is low, and especially fast, impurity is few in reaction, and product purity is high, and purity is higher than 99.5%, and yield reaches more than 95%, good in economic efficiency, is easy to suitability for industrialized production.
The synthetic method of pyromellitic trimethylsilyl chloride of the present invention, comprises the following steps:
(1) by trimesic acid and sulfur oxychloride under catalyst action, reaction;
(2) reacted rear first distillation and removed sulfur oxychloride, then underpressure distillation obtains pyromellitic trimethylsilyl chloride.
Wherein:
In step (1), the mol ratio of trimesic acid and sulfur oxychloride is 1:3.5~1:10, trimesic acid reacts mol ratio with the theory of sulfur oxychloride be 1:3, but sulfur oxychloride is simultaneously as solvent, so selecting both mol ratios is 1:3.5~1:10, can can accelerate speed of reaction again by sufficient reacting, and mol ratio while surpassing 1:10 solvent sulfur oxychloride too many, increased the energy expenditure of distilation steps, both wasted time and energy, increased again unit consumption, cost is increased, so reasonably proportioning is 1:3.5~1:10, wherein sulfur oxychloride is reaction raw materials and solvent, the present invention does not need additionally to add solvent, do not sneak into other solvent impurity, reduced the generation of polluting.
In step (1), temperature of reaction is 60~80 ℃, and the time is 5~15 hours.
In step (1), catalyzer is organic amine or quaternary ammonium salt phase transfer catalyst.
Catalyzer is preferably one or more the mixture in triphenylphosphine oxide, DMF, N,N-dimethylacetamide, benzyl triethyl ammonium ammonium halide or benzyl tributyl ammonium halide in step (1).The present invention is through creative experiments, and the preferred catalyzer of above suitable body series has advantages of that consumption is few, catalytic efficiency is high, easy separation and noresidue.Catalyst levels is 0.1%~3% of trimesic acid quality.
In step (2), distillation temperature is 120 ℃, and underpressure distillation pressure is-0.095MPa that temperature is 172~183 ℃.
In sum, the present invention has the following advantages:
(1) sulfur oxychloride is that reaction raw materials is used as again solvent, does not sneak into other solvent impurity, has reduced the generation of polluting.
(2) processing unit of the present invention is simple, energy consumption is little, cost is low, and the reaction of especially whole technique is quick, and impurity is few, and the product purity that distillation obtains is high, and content is greater than 99.5%, and yield reaches more than 95%, good in economic efficiency, is easy to suitability for industrialized production.
