Abstract: PURPOSE:To remarkably reduce the storage capacity by discriminating a group with a partial bit of the head of an input variable length code, outputting the bit of a variable length code except this partial bit as a fixed length part, and decoding this fixed length part with a group discriminating signal. CONSTITUTION:By a group classifying part 1, a group is discriminated with a partial bit of the head of an input variable length code, a group discriminating signal, and the bit of a variable length code except this partial bit are sent to a fixed length decoding part 2 as an address of a fixed length part, and a decoding signal is obtained. Subsequently, the number of bits by a fixed length part data FL is set as a fixed length part (f), and a group discriminating signal Gi from a ROM 14 and the fixed length part (f) from a separating part 16 and set as an address of a fixed length decoding part 17. Code length from this decoding part 17 is added to a shift control part 11-2 of an input part 11, and a shift of a shift register 11-1 is executed. Also, when the number of bits of the maximum code length increases, the number of groups can also be increased, therefore, in that case, the capacity of the ROM for constituting the decoding part 17 can drastically be curtailed.

Title: Production of chloromethyl pivalate
Inventor: YAMAGUCHI SATOSHI
IPC: C07B61/00
Filed: 1991-11-01
Abstract: PURPOSE:To industrially advantageously produce high-purity chloromethyl pivalate in a high yield useful as an intermediate of medicines, agicultural chemicals, etc., and showing a hue, a boiling point, etc., sufficiently satisfying the requirement for application thereto without using a reaction solvent. CONSTITUTION:In producing chloromethyl pivalate represented by formula (CH3)3CCO2CH2Cl by reacting pivaloyl chloride of formula (CH3)3CCOCl with paraformaldehyde (PFA) in the presence of a Lewis acid catalyst such as ZnCl2, the reaction is carried out in the presence of thionyl chloride as a cocatalyst without using a reaction solvent to obtain the objective compound in an industrially high yield. By this method, thionyl chloride is decomposed by water contained in PFA and the generated hydrogen chloride promotes the above- mentioned reaction. Water contained in the system is simultaneously consumed by thionyl chloride. By-production of pivalic acid can be inhibited and a small amount of by-produced pivalic acid can be converted to the raw material, pivaloyl chloride. Further, the yield per the reaction tank volume is remarkably high in industrial production since a reaction solvent is not used.
