Abstract: A process for the production of 3-hydroxyalkanals, more particularly 3-hydroxypropionaldehyde, by hydration of the basic 2-alkenals, more particularly acrolein, in the presence of a solid catalyst containing acid functional groups. The catalysts are based on an inorganic support containing basic activity centers (which are at least partly occupied by a polybasic acid, of which the first pKs value is between 0 and 3, in a form in which it cannot be removed by water) enables the hydration to be carried out with high selectivity. At the same time, the disadvantages of known organic fixed-bed catalysts are avoided. Preferred catalyst are based on pyrogenic titanium dioxide with phosphoric acid fixed thereon.

Granted: 1995-02-21
Abstract: A processing method of electromagnetic inductive digitizer includes the steps: 1. generating one 8.775K Hz frequency from the output end of CPU inside the hardware circuit of electromagnetic inductive digitizer, which can be emitted from the print circuit board attached inside the electromagnetic inductive digitizer or the conductive thin film. The CPU emits 8.755KHz scanning signal from its output end, and again selects next scanning signal line and emits 8.775KHz scanning signal, then the CPU judges if the inductive pen receives the signal. If yes, the CPU calculates the horizontal and vertical coordinates position touched by the inductive peon, then transmits the coordinate data to personal computer workstation through RS-232 serial interface; 2. if the CPU judges that the inductive pen don't receive the signal, then it checks if the sixty-second scanning line is emitted; if not yet, the step backs to the process of selecting the next scanning signal line by CPU; if yes, the step backs to the process of emitting 8.755KHz scanning signal by CPU.
