Fire retardant is then the effective auxiliary agent for changing high molecular material combustibility, and original flammable, inflammable material is made to have flame retardancy, disappear
Cigarette and self-extinguishment, can greatly fire preventing, preferably satisfaction safety in production and life requirement.Phosphate is as a kind of
Phosphorous ester type compound, it is many kinds of, it is widely used.According to the difference of added functional group, phosphate may be used as drug
Precursor, intermediate;It is used as the various additives such as adhesive, dispersing agent, curing agent, surfactant and fire retardant.
Phosphate has the advantages that low cigarette, nontoxic as a kind of organic halogen-free phosphorus-containing fire retardant agent in combustion, when use
It is more environmentally friendly, be recognized be alternative halogen containing flame-retardant one of staple product, have good development prospect.
It is mentioned in the documents such as Aleksandrsaka, Jan Michalski during Arbuzov Reaction mechanism obtains
Mesosome;GB1175211 mentions the substitution catechol ester obtained with phosphoric acid or phosphorus pentoxide;It is mentioned in the documents such as Von J
There is a unstable catechol esters chloride to dissociate to obtain intermediate;It is mentioned in CN 102086215B: the first step,
In chloroform, under the catalysis of triethylamine, heating makes catechol and phosphorus oxychloride reaction, and cyclization chemical combination is obtained after vacuum distillation
Object;Second step under the catalysis of triethylamine, above-mentioned ring compound is reacted with phloroglucin heating, decompression is steamed in chloroform
It evaporates and with being obtained after inorganic neutralizing treatment between three (1,3- dioxa -2- phospha -2- oxo -1,2- dihydro benzofuran) phosphoric acid
Benzenetriol ester.The use of chloroform and triethylamine increases subsequent processing steps.
Summary of the invention
It is good that the object of the present invention is to provide a kind of flame retardant properties, and the New-type halide-free for saving cost contains phosphorus type flame retardant,
The present invention can realize the green syt of this new flame retardant to avoid excessive postprocessing working procedures.
The present invention is achieved in the following ways: a kind of using catechol as the phosphate flame retardant of skeleton, it has
Structural formula shown in formula (1):
。
It is a further object to provide the environment-friendly preparation method thereofs of above-mentioned new flame retardant.
A kind of to prepare above-mentioned using catechol as the environment-friendly preparation method thereof of the phosphate flame retardant of skeleton, it includes following step
Rapid: the first step, under catalysts conditions, catechol is directly reacted with phosphorus oxychloride, is obtained among phosphoryl chloride phosphorus oxychloride after vacuum distillation
Body;Second step, in the molten state, phosphinylidyne chloromethylated intermediate and single phenol, diphenol, monohydric alcohol or diol reaction are obtained with adjacent benzene
Diphenol is the phosphate of skeleton.

Reaction temperature in the second step reaction is 50 ~ 180 DEG C, and the reaction time is 2 ~ 10 h.
The temperature of the vacuum distillation is 100 DEG C hereinafter, the time is 10-60 min.
In the first step reaction, the molar ratio of catechol and phosphorus oxychloride is 1:1 ~ 1:6.
In second step reaction, phosphinylidyne chloromethylated intermediate and single phenol, diphenol, monohydric alcohol or dihydric alcohol molar ratio be 1:1 ~
1:5.
In the first step reaction, catalyst [A]-x [Lewis acid], wherein A is amine and its derivative, imidazoles and its spreads out
Biology or pyridine and its derivatives;X is 0.2-2%, and x is the molar ratio of Lewis acid and A when synthesizing ionic liquid.
In the first step reaction, amine and its derivative are trialkylamine, and wherein alkyl is methyl, ethyl, propyl, fourth
Base, amyl, hexyl, heptyl, octyl, nonyl, isopropyl, isobutyl group or isopentyl;Imidazole and its derivants are imidazoles, N- alkyl
Imidazoles or 1,3- dialkylimidazolium, wherein alkyl is methyl, ethyl, propyl or butyl;Pyridine and its derivatives are pyridine, alkane
Yl pyridines or haloalkylpyridin, wherein alkyl is methyl, ethyl, propyl or butyl, and halogeno-group is chloro or bromo.It is described
Lewis acid is MgCl2、ZnCl2、SnCl2、AlCl3、FeCl3And TiCl4。
In the first step reaction, catalytic amount is the 0.001% ~ 0.01% of catechol quality.
It is reacted under negative pressure when raw material is single phenol or diphenol in the second step reaction, pressure is -0.01 ~ 0.01
MPa。
The utility model has the advantages that the present invention has synthesized a kind of novel halogen-free phosphorus-containing based flame retardant, starting point is obtained by Thermogravimetric Data
When solution temperature is 205 DEG C, when temperature reaches 800 DEG C, residual carbon content is 25% or more, and traditional phosphate resistance such as BDP, RDP
