[A novel sulfur compound, especially a fast-curing brimer containing aminopropyl and trifluoroethoxy groups in its molecule, which is useful as a coupling agent, a crosslinking agent for fluorine-containing materials, and a building aid. It concerns organosilicon compounds. (Structure of the Invention) The organosilicon compound of the present invention is represented by the general formula %, where R is an alkyl group such as a methyl group, an ethyl group, a propyl group, a butyl group, a cyclohexyl T-tx tonocycloalkyl group, a vinyl groups, alkenyl groups such as allyl groups, phenyl bridges, aryl groups such as tolyl groups, aralkyl groups such as benzyl groups, or carbon atoms of these groups (
Some or all of the double-bonded hydrogen atoms are replaced by halogen atoms,
An unsubstituted or substituted monovalent hydrocarbon group having 1 to 8 carbon atoms selected from a chloromethyl group substituted with a cyano group, a trifluoropropyl group, a cyanoethyl group, etc., where n is 0.1
or 2. Examples of this organosilicon compound include the following formula (%). The organosilicon compound of the present invention can be easily produced by, for example, reacting 2,2,2-trifluoroethanol with 2-cyanoethylorganosilane and then reducing the product with hydrogen in an autoclave in the presence of a cobalt agent such as Raney cobalt. (
You can wear two belts. As is clear from the above formula, this organosilicon compound contains a niaminopropyl group and a trifluoroethoxy group in its molecule, and this trifluoroethoxy group contains a methoxy group, an ethoxy group, an n- It has a high hydrolysis rate compared to propyl groups, and this hydrolysis rate increases even further when amines are present, making it a fast-curing carbon functional silane that can be used as an adhesive, and therefore as a brimer, and as a cup. It is said to be useful as a ring agent.It is also useful as a crosslinking agent for fluorine-containing materials and as a bone grafting aid because it contains a trifluoroethoxy group and has high compatibility with fluorine-containing materials. It should be noted that those with three trifluoroethoxy groups have a high compatibility with fluorine-based materials, Vf (: high, but those with two or one trifluoroethoxy group also have methoxy, ethoxy, etc. Since it has a higher hydrolyzability compared to other carbon functional silanes, it is said to be useful as a functional carbon functional silane.Example 1 2.2.2-) Refluoroethanol 33 ( 1(3,3
189 g (1.0 mol) of 2-cyanoethyltrichlorosilane was added dropwise into the reaction flask, and during the reaction (2) the generated hydrogen chloride gas was removed by flowing nitrogen gas, and even after the dropwise addition. After stirring at room temperature for 4 hours, hydrogen chloride was sufficiently removed under reduced pressure, dry evaporated urea was added to neutralize the remaining hydrogen chloride, and then residual urea and its hydrochloride were removed by r.
Separated. Next, the R liquid obtained in this way was condensed under reduced pressure and the excess 2.2.2-) refluoroethanol was distilled off.
15. ! Place it in an autoclave with i+, pressurize it with hydrogen, and then heat it to a temperature range of 80 to 100℃.
, pressure was reduced between 60 and 10 h/crl, and when the hydrogen pressure stopped changing, the autoclave was brought to room temperature and pressure, and the hemolyzed product was distilled. Elemental analysis, infrared absorption spectrum, and NMR spectrum were taken for this product, and when one molecule of sauce was measured by gas mass spectrometry, the following result was obtained. It was confirmed that it was 3-aminopropyltris+2.2.2-trifluoroethoxy)silane shown by [Elemental analysis] O, H, 4F, NO, SiOHSi
