Material etc. has important application.
Japan Patent JP5513825, JP2011068624, JP2016069643 and JP2016079405 report 9,9-
The preparation method of double [6- (2- hydroxy ethoxies) naphthyl] fluorenes, the synthesis step and result of these patents are all identical.The synthetic method
Using the concentrated sulfuric acid as catalyst, 3- mercaptopropionic acids are co-catalyst, by 9-Fluorenone and 2- (naphthyl epoxide) ethanol in xylene solution
In 60 DEG C stirring reaction 5 it is small when, after reaction with 48% sodium hydroxide solution wash and repeatedly wash, products therefrom purity
(HPLC analyses) 98.3%, yield 67%, these Japan Patents do not report product 9, double [6- (2- hydroxy ethoxies) naphthyl] fluorenes of 9-
Fusing point, crystal form and bulk density.This method consumes a large amount of sulfuric acid (sulfuric acid dosage is 4 times of moles of 9-Fluorenone).And need height
In concentration sodium oxide molybdena and wash, cause a large amount of spent acid contaminated wastewater environment.Big excessive 2- (naphthyl epoxide) ethanol is needed at the same time
Raw material (being more than 4 times of moles of 9-Fluorenone), recycling is difficult, and production cost is high.And double [6- (the 2- hydroxyl second of products obtained therefrom 9,9-
Epoxide) naphthyl] fluorenes yield is low, and purity is low (98%).
Japan Patent JP5330683, JP2009155253, JP2009173648, JP2011168721,
For JP2011168722 and JP2011168723 all using ethylene carbonate as hydroxyethylating agent, methylimidazole is alkali, in a contracting two
In 100 in ethylene glycol solvent oCMake double (2 hydroxy naphthalene base) the fluorenes hydroxyethylations of 9,9-.The synthesis step and result of these patents are all
It is identical.Reacting coarse product is obtained through recrystallisation from isopropanol, only obtains 61 grams of products from 1 mole of 9-Fluorenone synthesis, yield is only
11.3%.Purity 95.7%.Products obtained therefrom 9, double [6- (2- hydroxy ethoxies) naphthyl] the fluorenes yields of 9- are extremely low, and purity is low.While this
A little patents are also without report product 9, the fusing point of double [6- (2- hydroxy ethoxies) naphthyl] fluorenes of 9-, crystal form and bulk density.In order to gram
The shortcomings that taking above method, the present invention make the hydroxyl ethoxyl etherification of double (2 hydroxy naphthalene base) fluorenes of 9,9- with ethylene carbonate
In, suitable polar aprotic solvent is added, promotes the solubility of alkali in organic solvent, since solid liquid phase transfers to use, promote
Into ethoxyl etherification, the reaction time is shortened, it is suppressed that the formation of by-product polymer, simplifies post-processing step, together
When the three wastes largely reduce, yield increases substantially, and obtains double [6- (2- hydroxy ethoxies) naphthalenes of 9,9- of high-purity high-bulk-density
Base] fluorenes.
The content of the invention
The present invention is directed to above-mentioned deficiency, and the hydroxyl hydroxyethylation of double (2 hydroxy naphthalene base) fluorenes of 9,9- is made with ethylene carbonate
In reaction, suitable polar aprotic solvent is added, shortens the reaction time, it is suppressed that the formation of by-product polymer, letter
Change post-processing step, while the three wastes are largely reduced, yield increases substantially.The present invention provides high-purity high-bulk-density
