Title: Method for preparing glycol ester using reactive distillation
Inventor: CHOI JUN-TAE
IPC: C07C69/02
Filed: 2000-03-09
Granted: 2003-07-01
Abstract: Disclosed is a method for preparing glycol ester from glycol ether and carboxylic acid in the presence of a strong acid cation exchange resin. The catalytic reaction is implemented in a first reactive distillation tower which is maintained at a temperature of 50 to 150 DEG C under a pressure of 10 to 700 mbar. The reaction of the reactive distillation is separated into glycol ester, and unreacted reactants. The glycol ester is drained out through a lower part of the distillation tower while the unreacted reactants are directed to a second distillation tower from which they are reclaimed as raw materials. The use of the solid catalyst does not require a process for separating the catalyst from the reaction. The removal of the product by taking advantage of the reactive distillation tower improves the conversion rate of glycol ether without being limited by the equilibrium in the first distillation tower, greatly improved the production yield of glycol ester.

Inventor: BIERHOFF WALTHERUS CORNELIS JO
IPC: G11B7/22
Filed: 2000-04-26
Granted: 2001-11-21
Abstract: The invention relates to a method of manufacturing a scanning device comprising a support (9) for an information carrier (1), a motor (13) for rotating the support about an axis of rotation (11), a scanning unit (15) for scanning the information carrier, and a displacement device (19) for displacing the scanning unit relatively to the information carrier. According to this method, the motor and the displacement unit are each provided on a separate frame (29, 31), and the scanning device is provided with a pretensioning means (39) and an adjusting device (33, 35, 37). In at least one adjustment position, the frames are held at a mutual distance under the influence of a pretensioning force exerted by said pretensioning means, said distance being adjusted by means of said adjusting device. The adjusting device is used to correct an angular deviation present between a laser beam path (27) of the scanning unit and a normal to an information surface (7) of the information carrier as a result of manufacturing tolerances. According to the method in accordance with the invention, an adhesive (73, 75) is applied between the two frames adjoining the adjusting device, and the distance between the two frames, as adjusted by means of the adjusting device, is secured by curing the adhesive present between the two frames. In this manner, unwanted mutual displacements of the two frames, which could occur as a result of imbalance forces caused by the information carrier rotating at relatively high speeds, are prevented as much as possible.
