Abstract
This invention provides a method for producing a polycyclic aromatic vinyl compound which is hardly obtained by a usual method for separation/purification. This method for obtaining the high purity polycyclic aromatic vinyl compound comprises adding an adding agent such as a halogen, a hydrogen halide or water, to the vinyl group of the polycyclic aromatic vinyl compound such as divinylnaphthalene, divinylbiphenyl, acenaphthylene, to form a corresponding polycyclic aromatic vinyl compound derivative, purifying the polycyclic aromatic vinyl compound derivative by a recrystallization, an adsorption or an adduct separation and then releasing the adding agent added to the polycyclic aromatic vinyl compound.
Description
Technical field
The present invention relates to high purity ground and make the method for the polycyclic aromatic acetyl compounds of uses such as electronic material, optical material.
Background technology
Polycyclic aromatic acetyl compounds can be given the character of high heat-resisting, low-k, low-dielectric loss, high refractive index, fire-retardant and low moisture absorption etc. to various high molecular polymers, is expected to utilize in the field of wide range.For example, the spy opens flat 08-048725 communique with the raw material of vinyl biphenyl as the high resin of high refraction and thermotolerance.In addition, the spy opens the 2002-018293 communique and discloses the raw material use of divinyl biphenyl as the high Zeo-karb of thermotolerance.In addition, the spy opens 2001-294623 communique use acenaphthylene as giving the material of flame retardant resistance.
Polycyclic aromatic acetyl compounds can adopt the manufacturings such as dehydrogenation of coupling, cyclisation or the ethyl Ppolynuclear aromatic of monocyclic aromatic vinyl compound, but because any method all contains desirable polycyclic aromatic acetyl compounds impurity in addition, therefore expectation improves product purity.Especially, use the occasion of polycyclic aromatic acetyl compounds as polymer raw material, the performance reduction owing to the intensity that can make the polymkeric substance that is generated, thermotolerance, dielectric characteristics etc. so must improve purity, makes it not contain as far as possible the impurity that does not have vinyl.
Yet,, therefore in fact can not in the process of using monocyclic vinyl compound production high purity product, distill because the polycyclic aromatic acetyl compounds boiling point is high and polymerization easily.For example, in the Te Kaiping 11-140001 communique, when distilling vinyl compound down for 65～150 ℃, add N-nitroso-group-N, the nitroso compound of N '-diamyl Ursol D etc. prevents the polymerization of vinyl compound as stopper, but because polycyclic aromatic acetyl compounds generally is a high boiling point, so require the distillation under the ultrahigh vacuum(HHV), polymerization takes place in employed here stopper volatilization in distillation.
Te Kaiping 10-139696 communique has been put down in writing the high purityization of divinyl biphenyl utilization absorption, but will obtain the divinyl biphenyl near 100% with high yield, needs a lot of stage number, is not commercial run.And, even being cooled to-30 ℃, divinyl biphenyl do not separate out crystallization yet, therefore in fact can not adopt the cooling partial crystallization to improve purity.
The process for purification of hexene is disclosed in 71 pages of " vitochemical basis " (R.S.MONSON and J.C.SHELTON collaborate, and the Tokyo chemistry is issued with the people).The unsaturated link(age) part that this method utilization contains the hexene of the close impurity of boiling point is become dibromo-hexane by the bromine addition easily, boiling-point difference between dibromo-hexane and the impurity increases and makes that distillation is refining to become easily, and the bromine of affixture becomes hexene from the dibromo-hexane debrominate easily.Yet this method is difficult to apply to distill the separation of difficult polycyclc aromatic compound.
Summary of the invention
