Abstract
The invention discloses a method for synthesizing palm oil hard foamed polyether glycol. Palm oil and small molecular alcohol or amine compounds are taken as raw materials, and the method comprises the following steps of: obtaining qualified modified palm oil at certain temperature in the presence of a catalyst A; adding a certain amount of sucrose, a catalyst B and a propylene oxide (PO)/ethylene oxide (EO) mixture, and performing neutralization reaction with phosphoric acid or pyrophosphoric acid; and dehydrating to obtain the palm oil hard foamed polyether glycol. Compared with the conventional polyether glycol, the biobased polyether glycol prepared by the method has the characteristics of convenience in raw material purchase, capacity of being regenerated, low using amount of the PO and the EO, and low production cost, and can better meet the requirement of environmental protection.
Description
Technical field
The present invention relates to high molecular polymerization process, what be specifically related to is a kind of synthetic method of plam oil rigid-foam polyether polyol.
Background technology
The raw materials for production of traditional rigid-foam polyether polyol have glycerine, propylene glycol, Diethylene Glycol, ethylene glycol, sorbyl alcohol, tetrahydrofuran (THF), sucrose and propylene oxide, oxyethane etc., these products all are the byproducts of oil, because petroleum resources are Nonrenewable resources, along with expanding economy is petered out, make that the price of these products is higher.At present, the human dependence of wishing to reduce to oil improves environment.The exploitation of the polyvalent alcohol of green, environmental protection, economy has become an important directions of polyvalent alcohol exploitation.Based on this, people carry out relevant Products Development research with the natural resources of chemical research directional steering reproducible utilization, still find no the report that closes the present technique achievement in research at present.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, the synthetic method of the plam oil rigid-foam polyether polyol that a kind of raw material is easy to get, performance is good, pollution is little is provided.
The technical solution used in the present invention: the synthetic method of plam oil rigid-foam polyether polyol of the present invention, with plam oil, small molecular alcohol or aminated compounds is raw material, under the effect of catalyst A and certain temperature, form qualified modification plam oil earlier, the mixture that adds a certain amount of sucrose, catalyst B, propylene oxide (PO)/oxyethane (EO) again, by with phosphoric acid or tetra-sodium generation neutralization reaction after, through dehydration, need purified to make with extra care, finally make the plam oil rigid-foam polyether polyol, the quality index of plam oil rigid-foam polyether polyol:
Hydroxyl value: 300-550mgKOH/g;
Viscosity: 2500-10000mPas/25 ℃.
Described small molecular alcohol or aminated compounds can be ethylene glycol, propylene glycol, glycol ether, glycerine, tetramethylolmethane, a Virahol, diisopropanol, three Virahols, thanomin, diethanolamine, trolamine, alkyl ethanol amine etc. any one or more than one.
Described catalyst A and catalyst B can be alkalimetal oxide, alkali metal hydroxide, alkaline earth metal oxide, alkaline earth metal hydroxides, metal halide, any one of aluminum oxide etc. or more than one.
