Patent DE-4237379-A1 (DE)
Inventor: SOBOTTA GEORG DR ING
IPC: C07C51/12
Filed: 1992-11-05
Abstract: A process for the production of methyl formate by carbonylation of methanol in the presence of sodium methoxide or potassium methoxide as a catalyst is improved by reduction of the catalyst consumption and intensification of the process. For this purpose, a certain amount of sodium oxaperfluoro-alkanesulfonate or potassium oxaperfluoroalkanesulfonate and up to 10% by weight of strongly organic bases are added to the mixture for carbonylation. The reaction is carried out in a reactor having a circulation pump. The sodium salts, which are reaction products of the sodium methoxide, are removed by means of a filter. The filtrate is separated with the aid of rectification and the bottom product again subjected to carbonylation. The methyl formate results as the distillate, a high yield being achieved.

Title: Differential limit torque control device
Inventor: IIDA HIROKI
IPC: B60K23/04
Filed: 1994-02-11
Abstract: A device is proposed for controlling a differential limit torque which is generated in a differential provided in a motor vehicle. During vehicle deceleration a required value for the differential limit torque is calculated on the basis of the vehicle deceleration. If a reduction of the value of the required differential limit torque is then detected, a set value for the differential limit torque is then calculated by way of a filter process on the basis of the value of the required differential limit torque, a first filter being used which has a slow output response with respect to the reduction of the value of the required differential limit torque, or by means of a second filter which has a rapid output response with respect to the reduction of the value of the required differential limit torque without braking the vehicle. The differential limit torque is thereby adjusted to the calculated set value.
