Cis-3-hexenal-cis-3-hexenyl acetal compound, process for preparing same,

Disclosed herein are novel chloroacetanilide derivatives which act as remarkably effective herbicides when sprayed in a paddy field, the chloroacetanilide derivatives being 2',6'-diethyl-N-[(cis-alkenyloxy)methyl]-2-chloroacetanilides [A] represented by the general formula ##STR1## wherein R is a cis-form alkenyl group having 4 or 5 carbon atoms. Also disclosed are herbicide compositions for use in a paddy field and containing at least one of said chloroacetanilide derivatives [A] and at least one pyrazole derivative [B] represented by the general formula ##STR2## wherein R is a hydrogen atom or methyl group and X is a 4-toluenesulfonyl group or benzoylmethyl group; or-.alpha.-(2-naphtoxy)-propyonanilide [C] represented by the formula ##STR3##

Novel chloroacetanilide derivatives and herbicides containing the same

A process for producing a substituted phthalic acid which comprises heating a substituted tetrahydrophthalic acid compound having a substituent in at least one of the 3-, 4-, 5- and 6-positions in the presence of sulfur to dehydrogenate it, and heat-treating the product in the presence of water optionally together with an organic solvent. As required, the heat-treated product is dehydrocyclized to form a substituted phthalic acid anhydride.

Process for producing substituted phthalic acid compounds

Disclosed is an image processor that processes desired image data according to a program. In the image processor, the addressing desired pixels which is stored in an image memory is performed by an address processor, and a partial image taken out of the image memory by the address processor is written into a shared memory, and then data is drawn out from the shared memory by an operational processor to carry out operational processing. The address processor is provided with a buffer memory in which image data in a predetermined area is stored and successively renewed by an increment/decrement designation for read and write operations.

Programmable image processor

A radical polymerization initiator comprising as an active ingredient a hydroperoxide of disproportionated or hydrogenated rosin acid or its alkali metal or ammonium salt. The initiator is prepared by contacting disproportionated or hydrogenated rosin acid or its alkali metal or ammonium salt with molecular oxygen in water or an organic solvent at a temperature of 0.degree. to 150.degree.C. to form its hydroperoxide.
