Title: Two-stage production of polyol fatty acid polyester
Inventor: MARK STUART MILLER
IPC: C07H1/00
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a two-stage method for producing a lightly colored polyol fatty acid polyester having a high degree of substitution with a fatty acid group. SOLUTION: This two-stage method for producing a polyol fatty acid polyester comprises the first step which is a solvent-based esterifying reaction and the second stage that is a solvent-free esterifying reaction. In the first stage, a polyol in the solvent is reacted with a lower alkyl ester of a fatty acid at a relatively low temperature using an alkaline salt catalyst. When a desired degree of esterification is obtained, the resultant partially esterified polyol fatty acid polyester and the solvent-containing phase are separated. The separated partially esterified polyol fatty acid polyester is further esterified with the same or different fatty acid lower alkyl ester in the second stage with an alkaline salt catalyst using solvent-free high-temperature conditions. Thereby, the degree of substitution is increased.  Most of color bodies and other contaminants capable of producing color are removed with the solvent in the first stage and, therefore, are not present during the higher temperature reactional conditions in the second stage.

Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To deal with speed-up of a refresh rate of a recording medium by correcting an output current of a charge pump circuit according to the jitters detected from an input signal and a clock signal. SOLUTION: A signal EFM which is read from a recording medium and binarized and a clock signal PCK obtained by frequency-demultiplexing an output of VCO 5 are inputted to a phase-comparator 2 and a jitter detector 6. The jitter detector judges a deviation of a phase of a PCK edge to an EFM edge, and detects from a frequency difference between advanced edges and delayed edges. A correction current is generated according to the frequency difference, for correcting a charge pump 3 current outputted according to a result of the comparison by the phase-comparator 2. Following this, the current is converted into a voltage through a filter 4 and is supplied to VCO 5 as a control voltage. An oscillation frequency generated according to the control voltage of VCO 5 is frequency-demultiplexed and inputted to the phase comparator as a PCK signal.  Thus, it becomes possible to rapidly eliminate offset by composing a PLL loop.
