Abstract
The present invention relates to a method for preparing fatty hydrocarbon petroleum resin which is prepared by the cationic polymerization of C5 hydrocarbon as raw material under the catalysis of Lewis acid within the range of 0 to 60 DEG C. The C5 hydrocarbon as raw material comprises 20% to 80% of C5 olefin (comprising 10% to 70% of m-pentadiene and 90% to 30% of monoolefin) and 80% to 20% C5 saturated hydrocarbon.
Description
The present invention relates to the manufacture method of fatty hydrocarbon petroleum resin.
Fatty hydrocarbon petroleum resin is the big classifications of one in the petroleum resin, and it is by 20～80 ℃ of one section cut (C that obtain in the petroleum cracking process of producing ethylene
5Cut) through the cationoid polymerisation manufacturing, or with C
5Wherein some C that obtains after certain separation of cut process or the pure system
5Hydro carbons as raw material through the cationoid polymerisation manufacturing.In the manufacture method of existing fatty hydrocarbon petroleum resin, no matter raw material sources are C
5It is C that cut becomes
5Cut is through separating the C after purifying
5Hydro carbons all need add solvent in gathering reaction process, for example, United States Patent (USP) 3,987, No. 123 and 4,068, the manufacture method of the fatty hydrocarbon petroleum resin of No. 062 proposition promptly is at C
5Raw material carries out cationoid polymerisation after adding aromatic solvents such as benzene, toluene.
The purpose of this invention is to provide a kind of with C
5Hydro carbons is a raw material, directly makes the method for fatty hydrocarbon petroleum resin under the situation that does not add solvent through cationoid polymerisation.
For reaching above purpose, the technical solution used in the present invention is: will contain different C
5The component of hydro carbons is mixed to reach the C that contains following compositing range
5Raw material (% in this specification sheets all refers to weight percentage):
(1) C
5Alkene 20～80%,
(2) C

5Detailed hydrocarbon 80～50%.Above-mentioned C
5Raw material in the presence of Louis (Lewis) acid catalyst 0～60 ℃ behind cationoid polymerisation, with the aqueous sodium hydroxide solution termination reaction and wash with water, boil off unreacted C again
5Hydro carbons is also used steam distillation extracting oligopolymer, promptly obtains fatty hydrocarbon petroleum resin.
The C that the present invention proposes
5C during raw material is formed
5Monoolefine is different C
5The mixture of alkene, they can be: 2-first-2-butylene, 2-first-1-butylene, amylene-1, cyclopentenes, suitable-amylene-2, anti--amylene-2,3-first-1-butylene etc.
The C that the present invention proposes
5C during raw material is formed
5Stable hydrocarbon is different C
5The mixture of stable hydrocarbon comprises: Skellysolve A, pentamethylene, various isomerization pentanes etc.
The lewis acid catalyst that the present invention proposes is meant: aluminum chloride, alchlor, boron trifluoride and various complex compound, titanium tetrachloride, tin tetrachloride etc.
The present invention compares with existing fatty hydrocarbon petroleum resin manufacturing technology, adopts the C with suitable composition
5To be raw material directly carry out cationoid polymerisation to hydro carbons under the condition of solubilizing agent not, make manufacturing process obtain simplifying, and the petroleum resin that adopt the present invention to produce have and the same performance index (as indexs such as resin productive rate, softening temperature, colourities) of petroleum resin that have manufacturing technology production now.
Following examples will be further detailed the present invention.In these embodiments, the softening temperature of resin is by (the GB2294-80 standard is measured with ring and ball method, and the colourity of resin is to measure with adding nail (unit of length) (Gardner) method according to the GB1722-79 standard.
