Abstract

NEW MATERIAL:Isopropylbenzyl cyanoethyl ether of the formula. USE:An electrical insulating oil having a high dielectric constant, relatively good insulating property, dielectric stength, incombustibility and remarkably improved impregnating property compared with that of tricresyl phosphate (TCP). PROCESS:Isopropylbenzyl alcohol is reacted with acrylonitrile in the presence of an alkaline catalyst, e.g. NaOH, at ordinary temperature -70 deg.C to give the aimed compound. The addition of the acrylonitrile at one time in the reaction causes side reactions, e.g. the polymerization of the acrylonitrile. Therefore, the acrylonitrile is preferably added thereto in small portions.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to isobubyl benzyl cyanoethyl ether, a new compound having a high dielectric constant and relatively good insulation properties, and an electrical insulating oil containing this compound.

One of the most difficult things to miniaturize is a capacitor.
This is miniaturization. This is often the bottleneck in S quantification. Relatively high voltage such as 5% of oil run denner,
Since high-capacity capacitors are thick in shape and heavy in weight, their miniaturization greatly contributes to the miniaturization of the entire device, and miniaturization is strongly desired.

Further, it is preferable that the material has a high dielectric breakdown voltage. Examples of the conductive material include polyvinylidene heptatide, cyanoethyl amyl a-1. Materials having a dielectric constant of 10 to 25, such as cyanoethylated hydroxy cellulose, have already been developed. However, as electrical insulating oils are used as impregnating agents for these.

The dielectric constant of mineral oils and aromatic hydrocarbon oils used as highly insulating oils is 2.2 to 2.5, and the dielectric constants of mineral oils and aromatic hydrocarbon oils used as highly insulating oils are 2.2 to 2.5. Orthophosphate ester oil also has a dielectric constant of about 15 at most, which is considerably lower than that of the dielectric materials mentioned above.

Furthermore, in order to increase the capacity of the capacitor when assembled, the affinity (impregnability) between the dielectric material and the impregnating oil is also important. However, orthophosphoric acid ester oils with a relatively high dielectric constant such as tricresyl 7 phosphate (TCP) have poor affinity with polyvinylidene fluoride film, which is most commonly used as a dielectric material with a high dielectric constant. It is often difficult for the oil to uniformly wet the film surface, resulting in air bubbles remaining on the film surface and significantly lowering the withstand pressure of the condenser. Therefore, it is also preferred that the impregnating oil has good affinity with high dielectric constant films such as vinylidene heptafluoride films.

Also, its dielectric constant is within the range of an insulator, making it extremely useful as an insulating oil for DC capacitors. On the other hand, indyl cyanoethyl ether has a high dielectric constant but a low dielectric breakdown voltage (and conductivity is in the semiconductor region), making it unsuitable as an insulating oil.
