Title: Purification and recovery of methacrylonitrile
Inventor: OOHASHI HIROYUKI
IPC: C07C255/08
Filed: 1982-09-21
Abstract: PURPOSE:To obtain high-purity methacrylonitrile from the ammoxidation reaction product containing methacrolein and cyanic acid, economically in an industrial scale, by feeding the fraction distilled out under reduced pressure to the column to separate the low-boiling component. CONSTITUTION:The ammoxidation reaction product composed mainly of methacrylonitrile (abbreviated as MAN) and containing methacrolein and cyanic acid is absorbed with water, and the recovered MAN is distilled in the cyanic acid removing column 4a, the dehydration column 4b, the separation column for low-boiling component 6, and the product column 7 to recover the purified MAN. In the above process, the bottom liquid of the dehydration column 4b is introduced into the distillation column having reduced pressure, and the distillate from the column top is fed to the low-boiling component separation column 6 to obtain purified MAN. As an alternative method, the distillation in the dehydration column 4b is carried out under reduced pressure, and the gaseous distillate extracted from the bottom of the column is fed to the low-boiling separation column 6. EFFECT:The column bottom temperature can be lowered by the vacuum distillation to lower the decomposition rate of cyanhydrin and to suppress the contamination with the decomposed product. Cyanhydrin can be removed easily because the compound is discharged as a vapor phase.

IPC: G06T7/60
Filed: 1989-06-27
Abstract: PURPOSE:To reduce the load of a memory and to attain the scanner read even with a large quantity of graphic data by processing the run length data for each amount equal to one object. CONSTITUTION:A CPU of a scanner controller stores the run length data RL at and after the head of a memory M.
