Abstract
The invention discloses a phenyl phenol formaldehyde resin of large-hole strong alkali anion exchange resin catalyst, which is characterized by the following: adapting orthoxenol phenol and oxymethylene as raw material; proceeding condensation reaction under solid alkali catalyst; filtering in the final point to remove catalyst; distilling the filtrate to obtain the product. The invention saves some neutralizing, washing and extracting procedures without increasing waste discharge, which improves the product quality.
Description
Technical field
The present invention is a raw material with orthoxenol and formaldehyde, under the anion exchange resin catalyzed effect of macroporous strong basic, makes thermoset phenyl phenol formaldehyde resin through catalyzing and condensing, suction filtration, distillation.The technical field that belongs to phenyl phenol formaldehyde resin new catalytic synthesis technique.
Background technology
(name is 401 to the phenyl phenol formaldehyde resin
#Resin), outward appearance is thick reddish-brown liquid, viscosity 300-600CP (20 ℃), as foundry industry pasting of core agent commonly used, compare with the pasting of core agent of other type, all more satisfactory with indexs such as phenyl phenol formaldehyde resin institute its flex resistance of adherent core, pull resistance, flowability, ventilation property and set times.
The at present domestic existing mineral acid (hydrochloric acid that utilizes, phosphoric acid, oxalic acid, sulfuric acid, Phenylsulfonic acid), mineral alkali (sodium hydroxide, hydrated barta, ammoniacal liquor, zinc oxide), solid acid (macropore strong acid cation exchange resin) catalytic preparation phenols is the reported in literature of resin, the reported in literature that utilizes sodium hydroxide catalytic preparation phenyl phenol formaldehyde resin is also arranged, but existing phenyl phenol formaldehyde rosin products production technique is a raw material with orthoxenol and formaldehyde, under catalyst actions such as sodium hydroxide, through catalyzing and condensing, neutralization, washing, extraction, vacuum distilling makes, but wastewater flow rate is big in the art production process, serious environment pollution, and the neutralization of pH value adjusting operation easier is big, and quality product is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of new with the anion exchange resin catalyzed method of producing the phenyl phenol formaldehyde resin of macroporous strong basic, to overcome the deficiency that has the preparation method now.
Technical scheme of the present invention is: present method is a raw material with orthoxenol and formaldehyde, carries out condensation reaction under macroporous strong basic anionite-exchange resin (also claiming solid alkali) katalysis, filters the back filtrate distillation is made product.
The present invention includes following steps:
1) orthoxenol, dehydrated alcohol, the formaldehyde that measures is joined in three mouthfuls of containers or the flask successively, begin to stir, slow heat temperature raising, rotating speed is controlled at 50-100r/min;
When 2) mixeding liquid temperature reaches 25 ℃ in flask, add weight and be 50~70% phenyl phenol formaldehyde resin catalyst of orthoxenol, make itself and solution thorough mixing;
3) mixeding liquid temperature carries out the catalyzed reaction of 5-6h at 30~40 ℃ in the control flask;
4) after catalyzed reaction is finished, will react back solution suction filtration;
5) filtrate is put into new three mouthfuls of containers or a flask, 50-100r/min stirs, and adds thermal distillation, and distillation is earlier anhydrated and alcohol solvent, obtains phenyl phenol formaldehyde resin distillate at 85-110 ℃.
Above-mentioned orthoxenol and formaldehyde solid-liquid weight ratio 1: 1.3~1.4, the amount of alcohol solvent is the 35%-45% of orthoxenol and formaldehyde gross weight.
Above-mentioned orthoxenol is that 99% Industrial products, formaldehyde are that 37% chemical pure or technical grade product, ethanol are 95% chemical pure or technical grade product.
The invention has the beneficial effects as follows:
With orthoxenol and formaldehyde is raw material, under the anion exchange resin catalyzed effect of macroporous strong basic, carry out condensation reaction, reaction is finished after-filtration and is removed catalyzer, the filtrate distillation is obtained product, and the present invention has saved middle operation such as neutralization, washing, extraction, does not have newly-increased discharge of wastewater, do not need pH value to regulate, easy handling, good product quality are measured product viscosity 500-600CP (20 ℃) with digital rotary viscosity agent NDJ-5S.
