Abstract
The invention discloses a kind of preparation method to tertiary phenol methylene oxide resin.Its main technical points is to be catalyzer with the large hole cation exchanger resin, through right-tertiary phenol methylene oxide resin that condensation → filtration → distillation → cooling can be made.Have the technical process weak point than prior art, do not need toluene to make solvent, save operations such as neutralization, washing, extraction, decolouring.
Description
The invention belongs to a kind of preparation method of right-tertiary phenol methylene oxide resin.
Domestic existing production is right-and the method for tertiary phenol methylene oxide resin has two kinds, and a kind of is the base catalysis method, and a kind of is acid catalyzed process.The base catalysis method is that employing CaO or NaOH are catalyzer, all adopts the base catalysis method as units such as chemical plant, Shandong Province, Xinhua Resin Factory, Shanghai, Hong Wei chemical plant, Xiangfan, Hubei, chemical plant, jiangsu wuxi county, chemical plant, eternally happy shop, Beijing, Jinghai Jing Nan chemical plant, watt clouds chemical plant, Shanghai, chemical plant, granary, Jiangsu; Acid catalyzed process is that the employing mineral acid is a catalyzer, just adopts acid catalyzed process as chemical plant, Zhouzhuang, Jiangyin City, Jiangsu.The technology of alkalization method is:
There is following shortcoming in aforesaid method:
(1) because washing product per ton consumes 4～5 tons of ionized waters, forms waste water; Make solvent product per ton with toluene and consume 200 kilograms of toluene.
(2) need in producing with in oxalic acid decolouring, the acid and the toluene extraction, so technological operation is complicated.
(3) combined reaction intermediate controlled is difficulty relatively, how by experiential operating.
The foreign literature data also finds no the report of making catalyzer with large hole cation exchanger resin by retrieval.
Task of the present invention is the weakness that overcomes in the prior art, and the preparation method of right-tertiary phenol methylene oxide resin that a kind of technology is simple, cost is low is provided.
Technical scheme of the present invention is:
With right-tert-butyl phenol, formaldehyde is raw material, is catalyzer with the large pores cation exchange resin, sloughs water and low boilers through condensation reaction, vacuum filtration, vacuum distilling, and cooling then must right-tertiary phenol methylene oxide resin.Its reparation technology flow process is:
Embodiment:
With industrial goods right-tert-butyl phenol (content 〉=97%), large hole cation exchanger resin D
72, industrial formol (content 37%) adds in the reactor in proportion, heating, stirring, and condensation reaction was carried out in reaction in about 4 hours under reflux temperature.The proportioning of right-tert-butyl phenol and industrial formol is 1: 1, large hole cation exchanger resin D
72Add-on whether moderate fixed with pH value, be generally the 10-25% of right-tert-butyl phenol consumption, then with reaction solution vacuum filtration under the temperature of 50～60 ℃ of insulations, then filtered liquid is distilled under vacuum, to slough water and low boilers, cooling at last promptly gets right-tertiary phenol methylene oxide resin, and its softening temperature is adjusted as required.Large hole cation exchanger resin D
72Can reuse, unreacted reactant still can be sent into reactor and carry out condensation reaction.
Right-the tertiary phenol methylene oxide resin that makes with aforesaid method is faint yellow, and softening temperature is 90～95 ℃, 100～110 ℃ according to its scope of customer requirements, and in 54-1 neoprene adhesive prescription was measured, its stripping strength was 〉=15 kilograms per centimeter
2(1.5 hours).
Produce right-uncle's fluosite with the present invention and have following advantage:
1. technological process is short, and processing ease has been saved the operations such as neutralization, washing, extraction, decolouring than inorganic acid, base catalyzed reactions;
In the condensation reaction take water as solvent, replace originally take formaldehyde as solvent, the raw material source is easy to get.
Claims (3)
1, a kind of with right--it is right that tert-butyl phenol and formaldehyde condensation generate--method of tertiary phenol methylene oxide resin, feature of the present invention is in the condensation reaction to be that catalyzer replaces original base catalysis with the large pores cation exchange resin, with water is that solvent replacement toluene is solvent, and its preparation method is:
2, according to claim 1. described right-preparation method of tertiary phenol methylene oxide resin, the consumption that it is characterized in that catalyzer macroporous type resin cation (R.C.) is the 10-25% of right-tert-butyl phenol consumption.
3, according to claim 1. or 2. described right-preparation method of tertiary phenol methylene oxide resin, the unreacted reactant in catalyzer macroporous type resin cation (R.C.) and the condensation reaction is reusable.
