Definitions
- the present invention relates to a novel method for producing a isocyanurate cyclic structure material useful for producing a racket form.
- the isocyanurate cyclic structure substance is usually obtained by trimerizing an organic lithocyanate compound in the presence of a catalyst.
- trimerization catalysts JH Saunders and KC French: Polyurethanes, Chemistry and Tech-no loge (1962) p. 94, p. 94, are strong organic bases, for example, Calidate, Alkali metal phenolate, Alkali metal carbonate, tertiary amine, tertiary phosphine and N or P ⁇ Mich compounds and heterocyclic compounds of these elements are mentioned. It is also possible to use a reaction product of a Mannich base or a tertiary amide with an alkenyl ester of phosphoric acid, phosphorous acid or phosphonic acid. It will be known.
- the conventional trimerization catalyst has a problem that it is easy to give a yellow colored reaction product.
- the raw material is 2.4-trendylene isocyanate
- only the trimer can be selectively used without strict control of the reaction conditions such as the amount of catalyst, reaction temperature, and time.
- the reaction conditions such as the amount of catalyst, reaction temperature, and time.
- it is extremely difficult to obtain, and has the disadvantage of easily producing polynuclear bodies with poor solubility.
- An object of the present invention is to solve the above-mentioned problems in the production of a trimer of an organic silicate compound using a conventional catalyst.
- potassium fluoride can catalytically promote the trimer of the organic isocyanate compound. And reached the present invention.
- the present invention relates to a method for trimerizing an organic isocyanate compound, which comprises using, as a catalyst, fuichihikarime, preferably a polyethylene oxide compound, This is a method for producing an isocyanurate cyclic structural material characterized by using a quaternary ammonium salt and a Z or phosphonium compound together.

It intends from 0.1 to 40 hours or 1 second to several hours row ⁇ at room temperature ⁇ 0.99 e C a temperature of approximately. Since the fluorinated reams are hardly soluble in the above organic solvents,
- the target trimer (less than o.ig / _e), it can be easily recovered by filtration after the reaction.
- the target trimer is filtered, concentrated, and cooled. It can be easily separated and recovered from the solvent by known methods such as recycling.
- the fusidium calcium is directly dispersed in the organic isocyanate compound and reacted by heating, or the compound of (i) to (iii) is further added.
- fluorine fluoride loses its solvent activity in the presence of water, it is important to react under non-aqueous conditions, and because the presence of air suppresses the above-mentioned reaction, Preferably, it is performed in a vacuum or an inert gas atmosphere.
- the method for producing an organic silicate compound trimer according to the present invention has the following advantages as compared with the conventional method.
- trimer Since the side reaction hardly occurs, the raw material efficiency is excellent, and the obtained trimer is very easily separated and purified.
- 2,4-trilene diisocyanate is used as a starting material, only trimers are formed without polynuclear by-products, so that it has excellent solubility in solvents and is used as a paint. Good aptitude.
- 3Fluoridation power Remaining rim catalyst does not adversely affect product quality, so in most cases separation ⁇ Purification step is omitted Can be done.
- the amount of catalyst is extremely small, and it is economical to obtain a soft rim power rim industrially and inexpensively.
- a liquid oligomer having up to 70% of an isocyanate group having an isocyanurate cyclic structure is prepared by the method of the present invention, and this is reacted with a polyol. By doing so, a polyurethan containing an isocyanurate bond can be produced. This is useful as a form and elastoma.
- the solvent was removed from a commercially available 2.4-trialkylene citrate trimer (“Polyurethane 2030” manufactured by Polyurethane Industrial Co., Ltd. Japan).
- Polyurethane 2030 manufactured by Polyurethane Industrial Co., Ltd. Japan
- the product dried under vacuum under a nitrogen stream did not show a clear melting point up to 300 ° C, but this product showed a melting point of 130-135.
- the NC0 group content of the vacuum dried product of this commercial product was 15.0%.
- Example 2 0.5 g of Fitzinolium was added beneath the potassium fluoride, and the same treatment was carried out. After the reaction, the catalyst was filtered off, distilled at 2 mmHg, and gradually heated to 20 ° C., there was substantially no residue.
