  • Patent number: 9606991
    Abstract: In the conventional technology, a flag, which is for processing non-display of a certain comment according to existence or number of counts of deletion requests, is given to the comment in server side and distributed to the respective terminals. Therefore, there is a deficiency that comments with flags are not displayed in all users' terminals without exception. In order to solve the above deficiency, the present invention provides a comment distribution system, where a score is given to a comment to be distributed, the score is reduced in the distribution server according to registrations of inappropriate word from users as viewers, and a threshold is given with respect to each reproduction terminal and the score and the threshold are compared, thereby determining whether the comment is reproduced.

  • Patent number: 7166750
    Abstract: 5-[(4-chlorophenyl)methyl]-2,2-dimethylcyclopentanone is produced by reacting 1-[(4-chlorophenyl)methyl]-3-methyl-2-oxocyclopentanecarboxylic acid methyl ester or 1-[(4-chlorophenyl)methyl]-3-methyl-2-oxocyclopentanecarboxylic acid ethyl ester with sodium hydride and methyl halide, then hydrolyzing the obtained 1-[(4-chlorophenyl)methyl]-3,3-dimethyl-2-oxocyclopentanecarboxylic acid methyl ester or 1-[(4-chlorophenyl)methyl]-3,3-dimethyl-2-oxocyclopentanecarboxylic acid ethyl ester. The process provides 5-[(4-chlorophenyl)methyl]-2,2-dimethylcyclopentanone, an important intermediate of an agricultural or horticultural fungicide, e.g., Metconazole.

  • Patent number: 6916939
    Abstract: The present invention provides a process for production of a cyclic ester by depolymerization of an aliphatic polyester. In the process, a mixture containing the aliphatic polyester and a specific polyalkylene glycol ether, which has a boiling point of 230-450° C. and a molecular weight of 150-450, is heated under normal or reduced pressure to a temperature at which depolymerization of the aliphatic polyester takes place. Then, a substantially homogeneous solution phase, consisting of the melt phase of the aliphatic polyester and the liquid phase of the polyalkylene glycol ether, is formed. Heating of the solution phase is continued to form the cyclic ester by depolymerization and distil out the cyclic ester together with the polyalkylene glycol ether, and then the cyclic ester is recovered from the distillate. The present invention also provides a process for purification of a crude cyclic ester by use of the specific polyalkylene glycol ether described above.

  • Patent number: 5681979
    Abstract: The present invention provides a process for producing alkylcyclopentanone derivatives of formula (1) by reacting alkyl cyclopentanone derivatives of formula (2) and alkyl halides of formula (3) in an organic solvent in the presence of molecular sieves and an alkaline metal hydroxide: ##STR1## wherein R.sup.1 is C.sub.1 -C.sub.4 alkyl group; R.sup.2 is hydrogen atom or C.sub.1 -C.sub.5 alkyl group; R.sup.3 is C.sub.1 -C.sub.5 alkyl group; Y is halogen atom, C.sub.1 -C.sub.5 alkyl group, C.sub.1 -C.sub.5 haloalkyl group, phenyl group, cyano group or nitro group; n is an integer from 0 to 5; when n is 2 or greater, Y's may be identical or different; R.sup.3 in formula (3) is the same as R.sup.3 in formula (1); and a process for preparing alkylcyclopentanone derivatives of formula (5) by reacting cyclopentanone derivatives of formula (4) and alkyl halides of formula (6) in an organic solvent in the presence of molecular sieves and an alkaline metal hydroxide: ##STR2## wherein R.sup.1 is C.sub.1 -C.sub.

  • Patent number: 5646291
    Abstract: A process for manufacturing derivatives of 2-phenyl-4,5-oxazoledione 4-phenylhyrazone is disclosed. The process comprises reacting a derivative of a benezenediazonium salt, a hippuric acid derivative, and acetic anhydride in the presence of a neutralizing agent to effect the cyclization reaction for the formation of the oxazolone ring and the succeeding diazo-coupling reaction. The process does not require the conventional separate, independent step for the preparation of a solution of a hippuric acid derivative and acetic anhydride, thus eliminating the quick heating and quenching procedures and further avoiding the loss of the hippuric acid derivative due to decomposition of the oxazolone derivative. There is thus obtained a high yield of the desired product in a short period of time.

  • Patent number: 5279719
    Abstract: A process for chlorination of methylated aromatic compounds in a titanium tetrachloride is disclosed. The ring chlorination is first carried out by reacting said methylated aromatic compounds with chlorine gas under reduced light conditions, and then the side chain chlorination is carried out by reacting the resulting mixture with chlorine gas under light irradiation conditions. The process ensures continuous chlorination of aromatic rings and side chains of methylated aromatic compounds at a high yield without using any catalysts or perilous solvents such as carbon tetrachloride.
