摘要： PURPOSE:To improve flexible rigidity by impregnating paper with a liquid composition including the hydrolytic component of alkoxyl silane and an organic compound reactable with the hydroxyl group and then drying it. CONSTITUTION:The paper is impregnated with the liquid composition including the hydrolytic component of the alkoxyl silane and the organic compound provided with more than two functional groups reactable with more than two hydroxyl groups provided in the hydrolytic component and then is dried. The degree of hydrolysis is selected normally from 40-90% and preferably 60-80%. The monomer of 2-10wt.% is normally included in the obtained hydrolytic component, however, when the monomer is removed by the method of flash distillation and vacuum distillation, etc., until a monomer amount becomes less than 1wt.%, preferably less than 0.3wt.%, the obtained composition for a coating film becomes the one with extremely improved storage stability. As the organic compound reactable with the hydroxyl group, the ones provided with more than two of carboxyl group and amino group, etc., can be listed.

摘要： PURPOSE:To obtain a non-water-repellent coating film having high hardness and excellent flexibility by forming a coating film of an organic substance having a polysiloxane bond free from an Si-bonded alkyl group and having a specified Si content in the polysiloxane bond. CONSTITUTION:The coating film of an organic substance having a polysiloxane bond free from an Si-bonded alkyl group and an Si content of the polysiloxane bond of 20-90wt.% in terms of SiO2 is provided. This film is formed by reacting a hydrolyzate of an alkoxysilane with an organic compound having a functional group reactive with the hydroxyl groups of the hydrolyzate. This film has contradictory properties i.e., high hardness and flexibility, and as a result it has a beautiful appearance because of its staining resistance and can show scratch resistance because of its rigidity. Further it has no difficulty that the beautiful appearance is injured by the water repellency, which is common to a silicon-containing organic resin. Besides, a coating film having a thickness of 10mum or above can be obtained in one coating operation.

摘要： PURPOSE:To obtain a new physiologically active substance which is obtained from a culture mixture of a specific microorganism blonging to the genus Verticilium and useful as an antitumor agent with reduced side-effect, specifically inhibiting the proliferation of human-originating cancer cells without inhibiting proliferation of non-tumorigenic cells. CONSTITUTION:A microorganism belonging to the genus Verticillium, producing a novel physiologically active substance of formula I [R is H, OH; R is H, formula: CH2CH=C(CH3)2; R , R combine to together form group of formula II or III; R is H, OH; R -R are H, group of formula IV], for example, Verticillium balanoides MCI 2825 strain, is inoculated to a culture medium and cultured under shaking at 27 deg.C for 11 days. Acetone is added to the culture mixture to effect extraction and the extract is filtered with Celite, then the acetone is distilled off under reduced pressure, ethyl acetate is added to the residue to effect extraction and the extract is concentrated under reduced pressure. The oily residue is subjected to reverse-phase partition chromatography to effect purification, whereby the objective new physiologically active substance such as antitumor agent represented by formula I is obtained.

摘要： PURPOSE:To obtain formamide hardly containing any impurities by reacting a formic acid ester with ammonia in the presence of an alcohol under anhydrous and catalyst-free conditions. CONSTITUTION:A formic acid ester is made to react with ammonia in the presence of an alcohol of >=20wt.%, preferably >=30-100wt.% based on the formic acid ester at 10-40 deg.C, preferably 10-30 deg.C under anhydrous and catalyst-free conditions to provide the objective formamide. The formamide obtained by this method contains hardly any formic acid which acts as an acid, ammonium formate and diformamide, thus the method is optimum, especially for synthesizing N-(alpha-hydroxyethyl) formamide using a basic catalyst. Since formic acid produced when polyvinylamine is produced by hydrolyzing a polymer of N- vinylformamide is recovered as a formic acid ester and can be utilized as a raw material in the above reaction, this method has large merit in production fields of n-vinylformamide and polyvinylamine.

摘要： PURPOSE:To obtain the subject compound useful for an edible dispersant, etc., industrially and advantageously by reacting sucrose with a fatty acid alkyl ester in the presence of an alkali catalyst in a specific solvent while taking out the reaction mixture from the bottom of a reactor and circulating to the top of the reactor. CONSTITUTION:A reactor 1 equipped with an anchor-shaped agitator 2, a baffle plate 3 and a heating coil 4 is charged with an alkali catalyst (e.g. anhydrous potassium carbonate) and dimethyl sulfoxide as a reaction solvent. A recovered saccharide containing sucrose and a fatty acid alkyl ester (e.g. methyl stearate) are fed to the reactor, the solvent is heated by a heating coil 4 and boiled and the solvent vapor is condensed.refluxed by a fractionating column 8 and condensers 9 and 10 to carry out reaction. The reaction is carried out while taking out the reaction mixture from the bottom of the reactor through an extracting valve 5 and circulating through a pump 6 and an outer circulating line 7 to the top of the reactor during the reaction to industrially and advantageously obtain the objective sucrose fatty acid ester useful as an edible dispersant.
