The present invention relates to a method for producing a water-soluble high molecular weight polyalkylene ether polyol. Water-soluble high molecular weight polyalkylene ether polyols have traditionally been useful compounds that have a wide variety of uses as water-based hydraulic oils, cutting oils, and rolling oils.
In these applications, in order to prevent fires caused by leakage of oil-based substances, formulations that maintain a constant viscosity and increase the amount of water added are gradually increasing. There is a need to improve the performance of the water-soluble compounding agents used, ie, the performance of water-soluble high molecular weight polyalkylene ether glycols that provide high viscosity in aqueous solutions. The performance referred to here means the concentration of the aqueous solution necessary to provide a constant viscosity. The condition for providing this performance is to increase the (average) molecular weight of the polyalkylene ether polyol including polyalkylene ether glycol, that is, to increase the molecular weight. However, in the production of water-soluble high molecular weight polyalkylene ether polyols using ordinary basic catalysts, a large amount of by-product polyalkylene ether glycol is generated on the low molecular weight side due to the basic catalyst itself or the generation of unsaturated bonds, and the apparent Despite the increase in viscosity, water solubility does not improve, and because the product is designed to have a higher molecular weight than necessary, there are drawbacks such as difficulty in mechanical shear resistance. The present inventors have conducted extensive research in view of the above-mentioned actual circumstances, and as a result have come to provide the present invention. That is, in the method for producing a water-soluble high molecular weight polyalkylene ether polyol, at least 30% by weight of a compound having 26 or less carbon atoms and having at least one aliphatic hydroxyl group (hereinafter referred to as starting material) is ethylene oxide. This is a method for producing a water-soluble high molecular weight polyalkylene ether polyol, which comprises co-addition polymerizing an alkylene oxide and 1 to 20% by weight of glycidol based on the alkylene oxide in the presence of a basic catalyst. Starting materials that can be used in the present invention include, for example, aliphatic alcohols having 26 or less carbon atoms such as methanol, ethanol, butanol, and 2-ethylhexanol, glycerin, tolmethylolpropane, pentaerythritol, sorbitan, sorbitol, sucrose, etc. These include aliphatic polyhydric alcohols. Next, the alkylene oxide used in the present invention is
It contains at least 30% by weight of ethylene oxide, and more specifically, ethylene oxide alone or in combination with other alkylene oxides as needed within the above ratio. Other alkylene oxides used in the present invention include aliphatic alkylene oxides having 10 or less carbon atoms, such as propylene oxide, butylene oxide, cyclohexene oxide, and nonene oxide. In order to obtain the water-soluble high molecular weight polyalkylene ether polyol of the present invention, the proportion of ethylene oxide in the total alkylene oxide should be
At least 30% by weight, preferably from 50 to 80% by weight is required. When the proportion of ethylene oxide is less than 30% by weight, the solubility in water rapidly decreases, making it unsuitable for the intended use. Next, the glycidol used in the present invention is a commonly used and known glycidol. The amount used is 1 to 20% by weight, preferably 3 to 20% by weight based on the alkylene oxide.
It is 10% by weight. Next, the basic catalyst used in the present invention is, for example, an alkali metal hydroxide such as caustic potash or caustic soda,
or alcoholates thereof, or salts of alkali metals and alkaline earth metals. The amount used is 1% by weight or less based on the target product, preferably
It is 0.5% by weight or less. In the present invention, high molecular weight means that the peak top position as measured by gel permeation chromatography is 20,000 or more. Therefore, the water-soluble high molecular weight polyalkylene ether polyol also has a peak top position of 20,000 or more as measured by gel permeation chromatography. 10,000 or more, preferably 40,000 to 100,000. According to the production method of the present invention, first, an alkylene oxide containing at least 30% by weight of ethylene oxide as a starting material and glycidol in an amount of 1 to 20% by weight relative to the alkylene oxide are co-addition polymerized to form a water-soluble high molecular weight polyalkylene oxide. Prepare an ether polyol. The addition polymerization form may be either block type or random type. Such an addition reaction, in the presence of a basic catalyst, takes approximately
It is carried out at a temperature of 100-150°C for about 20-100 hours. Further, the water-soluble high molecular weight polyalkylene ether polyol obtained by this reaction is prepared so as to exhibit a peak top position of 20,000 or more by gel permeation chromatography. The production method of the present invention configured as described above includes (1) suppressing the generation of low molecular weight to a minimum under normal basic catalysts, (2) producing high quality and when compared with normal ones,
A novel water-soluble high molecular weight polyalkylene ether polyol is obtained which exhibits excellent viscosity properties.
Therefore, it has characteristics such as being able to be developed into new application fields, including excellent water-based hydraulic oil, cutting oil, rolling oil, etc. Next, the present invention will be explained in more detail with reference to Examples and Comparative Examples, but the present invention is not limited to these Examples. In addition, in the examples 〓%〓
and 〓part〓 are based on weight. Example 1 The starting materials were placed in an autoclave, a basic catalyst was added, and the mixture was heated and dissolved. After purging the inside of the autoclave with nitrogen, alkylene oxide and glycidol pre-mixed at a gauge pressure of 1 Kg/cm 2 were introduced. The reaction was completed. Next, after cooling to 80°C, the product was taken out, and 1/10 of it was returned to the autoclave, and the mixed alkylene oxide and glycidol were introduced again to complete the reaction. After repeating this operation several times, the mixture was cooled to 80°C and neutralized by adding acetic acid in a molar ratio commensurate with the added basic catalyst to obtain a water-soluble high molecular weight polyalkylene ether polyol. Various water-soluble high molecular weight polyalkylene ether polyols were prepared in the same manner. They are shown in Table 1.
