  • Method for producing 7h-pyrrolo[2, 3-d]pyrimidine derivative and intermediate thereof
    Patent number: 10822354
    Abstract: The present invention provides a method for producing a 7H-pyrrolo[2,3-d]pyrimidine derivative that is useful as a janus kinase (JAK) inhibitor; an intermediate of the 7H-pyrrolo[2,3-d]pyrimidine derivative; and a method for producing the intermediate. The present invention provides a method for producing 3-[(3S,4R)-3-methyl-6-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1,6-diazaspiro[3.4]octan-1-yl]-3-oxopropanenitrile, which uses a salt of an organic acid and (3S,4R)-3-methyl-1,6-diazaspiro[3.4]octane-1-carboxylic acid benzyl.

  • Combustion system
    Patent number: 10563863
    Abstract: A combustion system is capable of using a petroleum pitch fuel, and is provided with a burner having a fuel supply pipe where a flame stabilizing plate is formed in a tip end of the same, and a high temperature maintaining unit for maintaining an atmosphere temperature at a vicinity of the flame stabilizing plate during operation higher than a softening point of the petroleum pitch fuel. Thus, even when the petroleum pitch is used as fuel, the burner does not become unusable due to adhesion/solidification of the petroleum pitch inside the burner and combustion operation can be continued for a long time.

  • Method for producing trifluoroethylene
    Patent number: 5283379
    Abstract: Method for producing TrFE by reaction of R-113 with hydrogen in the presence of a catalyst comprising palladium and at least one selected from gold, tellurium, antimony, bismuth, and arsenic, supported on an inert carrier. TrFE can be produced from R-113 and hydrogen through one-step reaction by use of the catalyst.
