Description
Technical field
The invention belongs to the resource application field of C8, C9 fraction and coal tar light fraction in petroleum cracking and reformation, tools
Body is related to one kind with these mixture fractions directly with maleic anhydride (MAH), maleimide and its derivative, itaconic anhydride
Or several reactions prepare functional copolymer.
Background technique
C8 and C9 fraction is mainly derived from preparing ethylene by steam cracking technique and naphtha platforming technique, some comes
Derived from toluene disproportionation or transalkylated product and coal tar etc., their composition is shown in Table 1~4.
Table 1.C8 fractional composition
Table 2.C9 fractional composition
The C9 fractional composition of 3. different manufacturers of table
4. coal tar light fraction of table composition
It includes styrene, phenyl allyloxy, vinyltoluene, indenes, first indenes that C8 fraction, which mainly contains unsaturated hydrocarbons, seen from table 1
Deng it is dimethylbenzene/ethylbenzene (accounting for 60%-65%), styrene (30% or so) that main component, which can be obtained, in its further rectifying
Mixture.C9 fraction is a kind of C9 aromatic hydrocarbons and alkene mixture, and there are mainly two types of sources: one is C9 is reformed, mainly being come
From the reformer hexichol tower bottom oil of oil plant；There are also one is the by-products from ethylene production.As can be known from Table 3, no
Each constituent of C9 fraction with producer is roughly the same.Crack C9Contain a large amount of unsaturated hydrocarbons in fraction, ingredient is very multiple
It is miscellaneous, and boiling point is close, and causes the difficulty finely separated larger.With the fast development of the petrochemical industry in China, generation
The yield of the ethylene of table Industry Development Level also increases significantly, thus the yield of the C8 and C9 fraction as Crude products.deep process also with
Increase.Therefore, the mixing by-product of high carbon number how has been effectively utilized, also at an important class in petroleum industry
Topic.
Light oil constituents in coal tar mainly contains styrene, α-methylstyrene, alkylbenzene, vinyltoluene, bicyclic penta
Diene, benzofuran, indenes, first indenes and methyl benzofuran etc., at present mainly as the coumarone indene resin raw material of dark-light color.
Currently, the C8 fraction in China is mainly for the production of paraxylene, blended gasoline and solvent, wherein paraxylene is raw
The basic material of polyester is produced, and unsaturated mixture therein is not utilized also such as styrene and derivative.With close
The production capacity of ethylene is gradually increased over year, so that the advantage of extracting phenylethylene is more obvious from drippolene, and C8 fraction
In contain more styrene, so C8 extracting phenylethylene technology more and more attention has been paid to.The C8 extracting phenylethylene first step is to want
By selective hydrogenation reactor, so that the phenylacetylene in C8 fraction is selectively converted into styrene, then pass through extraction
Rectifying separates styrene and others C8 component.C8 extracting phenylethylene process route is longer, has in actual operation very big
Difficulty, first is that styrene and ortho-xylene relative volatility are minimum in C8, second is that can have micro phenylacetylene in styrene,
Third is that product styrene can have color due to purity.These technical difficult points all limit C8 extracting phenylethylene technique
Development.
Currently, more commonly application is the C9 petroleum for synthesizing Aromatic Petroleum Resins and using as solvent to C9 fraction
Resin is a kind of thermoplastic resin, and molecular weight is about between 300-3000.The production technology of C9 Petropols mainly includes catalysis
Three kinds of polymerization, free radical polymerization and thermal polymerization modes, wherein catalytic polymerization is most common polymerization.Polymerization reaction temperature
Degree is generally set to 50 DEG C or so, and the reaction time, reaction temperature and reaction time were all unsuitable excessively high in 1-5h or so.Industry at present
Upper most widely used catalytic polymerization is the acid catalyzed polymerisation technique using Lewis acid as catalyst, the catalytic polymerization
The advantages of technique is that polymerization speed is fast and adjusting is mild, but a large amount of industrial wastewater is easy to produce in Removal of catalyst.
It is described in US.NO.6479598 in the catalyzed polymerization process of C9 fraction, wraps up catalyst on a catalyst support, to save
Recycling and the last handling process of catalyst are fallen.But in daily industrial production, since production C9 Petropols technique is multiple
Miscellaneous, production line is longer, and is easy to produce a large amount of industrial wastewater, so the production popularity rate of C9 Petropols is very low always, this
Greatly limit the recycling of C9 fraction resource.
