Description
Technical field
This utility model belongs to the preparation field of chemistry carboxylate, trial assembly in more particularly a kind of plasticizer of mixed ester
Put.
Background technology
Pyromellitic acid anhydride, is called for short PMDA, is a kind of important industrial chemicals, is widely used as intermediate.All benzene four
Formic acid dianhydride is prepared with air gaseous oxidation by durol.Owing to course of reaction existing selectivity of catalyst,
Activity, the various factors such as the control of reaction condition and exchange of reaction heat, thus there will be side reaction in various degree,
Causing containing impurity in the pyromellitic acid anhydride product obtained, these impurity are cis-butenedioic anhydride, inclined acid anhydride, dimethyl phthalic anhydride and durene quinone
Deng, content is all between 2%-5%.If these impurity are not used, not only result in the pollution of environment, and waste a large amount of
Important resource.And diisooctyl maleate and the different monooctyl ester of trimellitic acid three are all the plasticising that performance is the most excellent
Agent, is also critically important industrial chemicals simultaneously.
Diisooctyl maleate is a kind of important fine chemical product, can be used for coating, binding agent, rubber, stone
The aspects such as oil additive, are also the main intermediate of synthesis penetrating agent, and itself also has good permeability, grinding at insecticides adjuvant
System plays a very important role.
The different monooctyl ester of trimellitic acid three (being called for short TOTM) is the plasticizer that a kind of performance is the most excellent, has volatility little,
Animal migration is low, Heat stability is good, has the features such as the fabulous compatibility and processability with polrvinyl chloride, can be widely used in polychlorostyrene second
The processing aid of the various kinds of resin such as the copolymer such as alkene, polyethylene, celluloid, cellulose acetate, cellulose butyrate, the suitableeest
For manufacturing heatproof, electrical insulating property requires high polyvinyl chloride resin electricity plastics；Phthalic acid di-isooctyl (being called for short DOTP) is polychlorostyrene second
Alkene new plasticizer, extraction heat-resisting, cold-resistant, anti-, flexibility is good and PVC has the good compatibility.
The liquid acid such as esterification concentrated sulphuric acid are as catalyst, although catalysis activity is high, response speed is fast, but easily
Generation three-waste pollution, etching apparatus are serious, product is difficult to reclaim.The liquid acid catalysts such as concentrated sulphuric acid are badly in need of being substituted.With
The raising of people's living standard, environmental conservation is proposed the highest requirement.
1979, the Hino of Japan really et al. successfully synthesized for the first time without any halogen can be at 500 DEG C of high temperature
The SO42-/WxOy type solid super-strong acid of lower application.It is with some metal-oxide as carrier, consolidating with SO42-as loaded article
Body catalyst.Later, wolframic acid and molybdate dipping ZrO2 were prepared WO3/ZrO2, MoO3/ZrO2 solid super strong again by Arata etc.
Acid, although its acidity is more slightly lower than SO42-/ZrO2 but still stronger 100 times than 100%H2SO4.Owing to this kind of solid super-strong acid holds
Easily preparation and preservation, particularly it is compared with halogen-containing solid super-strong acid in liquid acid, has not etching apparatus, does not pollute ring
Border, can at up to 500 DEG C the feature such as use, cause people and obtain broad interest.Root is according to the literature, it has been found that this kind of
Alkane isomerization, olefines double bond isomerizing, esterification, dehydration of alcohols, acylated, polymerization, methane ethylene are gathered by halogen-free solid super-strong acid
Many reactions such as conjunction, lique faction of coal all show the highest catalysis activity, even also show that some reaction at normal temperatures very
High activity and selectivity, illustrates that they are very promising new catalytic materials of class.Document report SO42-/
ZrO2-Fe2O3-SiO2 is successfully prepared butanoic acid acetonyl ester, and rare-earth solid superacid SO42-/TiO2/La3+ successfully synthesizes horse
Carrying out dibutyl phthalate, SO42-/ZrO2-TiO2 is successfully prepared Fructus Fragariae Ananssae ester etc..SO42-/TiO2 has good catalysis activity, as
Fruit adds Al in preparation process, can improve catalytic performance, carry out Pyromellitic Acid four with SO42-/TiO2-Al2O3 different
The preparation of monooctyl ester has had document to report.
Some external developed countries, the high-carbon plasticizer produced such as the country such as the U.S., West Europe is evolving, and yield is not
Disconnected increase, and the production of China's current more than C9 high-carbon plasticizer alcohol is the most blank.There is the equal benzene tetramethyl of set more than 70 in the whole nation at present
Acid device, the most about produces more than 100,000 tons C10 mixed acid anhydride by-products, and current its by-product of all production enterprises is all committee
Torr fixed-end forces company processes, and processing cost is high, does not meets cleaning production, energy-saving and emission-reduction, the social consensus of recycling economy and warp
Ji theory, does not more play the using value of its by-product, causes the wasting of resources, if its by-product can comprehensively utilize
Come, on the one hand can produce certain economic benefit, on the other hand can reduce environmental pollution.
The technique of terephthalic acid residue production DOTP is in yueyang, hunan petrochemical plant industrialized production, and it is industrial
Change product index and reach the standard of domestic like product.DOP, TOTM, TOPM technique document all has been reported that, and has built up work
Industry process units.So, with mixed acid anhydride and isooctanol, the esterification as raw material is theoretically feasible.With equal four
Toluene oxidation its by-product C10 mixed acid anhydride be Material synthesis plasticizer of mixed ester be a kind of novel compound plasticizer, mixed
Compound possesses the character of one-component material, and mixed ester has the plasticising performance of mono-ester component, and has compound plasticising effect
Really.
