- Diamino compounds and their production method
-
The present invention is to provide diamino compounds useful to polyamide raw materials for production of liquid crystal alignment layers having excellent voltage holding ratios without development of image-sticking phenomena, a method for producing the compounds and liquid crystal display devices equipping the liquid crystal alignment layers. The Diamino compounds are represented by the general formula (1): STR1 wherein R indicates hydrogen or an alkyl group having 1 to 8 carbon atoms, further, X, Y and Z indicate hydrogen, an alkyl group having 1 to 3 carbon atoms or fluorine, respectively, and a part or all of them may be the same or different, and the positions of these substitutive groups may be ortho positions or meta positions.

- Process for making a silylisocyanurate
-
This invention provides a process for making a silylorganocarbamate or a silylisocyanurate which process comprises reacting an aminosilane with a dialkyl carbonate, diaryl carbonate or a mixture thereof in the presence of a basic catalyst to obtain the silylorganocarbamate; optionally, neutralizing the basic catalyst and residual aminosilane with a neutralizing agent; and adding a cracking catalyst and heating at subatmospheric pressure to obtain the silylisocyanurate; or heating a silylorganocarbamate at a temperature sufficient for dissociation of the carbamate at subatmospheric pressure in the presence of a cracking catalyst and a timerization catalyst to obtain a silylisocyanurate.

- Process for making amino group-containing organosilicon compounds
-
A process for making an organosilicon compound containing an amino group, which comprises reacting an allylamine with the hydrosilyl group of a silicon compound represented by the formula: wherein R1 represents monovalent groups which may be identical of different and are selected from the group consisting of substituted or unsubstituted hydrocarbon groups, di- or trimethylsilyl groups and mono- or polyorganosiloxanyl groups; R2 represents an alkoxy-substituted or unsubstituted alkyl group; and n represents an integer of 0 to 3, in the presence of a complex of platinum with an olefin or its derivative, said reaction being carried out further in the presence of an amino compound represented by the formula: wherein R3 represents monovalent groups which may be identical or different and are selected from the group consisting of hydrogen, alkyl groups and phenyl groups, at least one of which is an alkyl group or a phenyl group; Q represents a divalent group of the formula: STR1 of which two valences are bonded to the same N atom; and A represents O or S.
