    摘要: This invention relates to a process for preparing 2-chloropropionaldehyde (2-CPA) by using vinyl chloride, carbon monoxide and hydrogen as raw materials. Although processes making use of cobalt catalysts have conventionally been known, it is disclosed herein that by using a rhodium compound and a nitrogen- or phosphorus-containing Lewis base in combination as a catalyst, the reaction is allowed to proceed at temperature and pressure lower than those required for such conventional processes and the selectively toward the intended product is improved. It is also disclosed that by causing water to exist in the reaction system and using a water-insoluble organic solvent, fractionating the reaction mixture into a water layer and an organic layer after the reaction and then collecting 2-CPA from the water layer through distillation, extraction or the like, the rhodium compound contained substantially in its entirety in an organic layer can be reutilized in the form of its solution. This process is an extremely good process suitable for use in the preparation of 2-CPA which is useful as an intermediate for chemical products, agricultural chemicals, pharmaceutical products, etc.

    摘要: In the production of 2-chloropropionaldehyde by the hydroformylation of vinyl chloride in the presence of a rhodium catalyst in combination with a base, the activity of the catalyst can be improved significantly by maintaining the concentration of produced 2-chloropropionaldehyde in the reaction solution at not higher than 10%.Further, it is possible to continue the reaction for a long period of time while maintaining the activity of the catalyst at a high level by carrying out the reaction in a water insoluble or hardly soluble solvent simultaneously with water extraction, separating the catalyst solution and the extraction water from each other, separating 2-chloropropionaldehyde from the extraction water by distillation or similar means so as to lower its concentration to a given level or below, and using the extraction water again after subjecting it to an anion exchange treatment.

    摘要: According to one embodiment, a method is disclosed for manufacturing a semiconductor light emitting device. The method can include forming a nitride semiconductor layer including a light emitting layer on a first substrate having an unevenness, bonding the nitride layer to a second substrate, and separating the first substrate from the nitride layer by irradiating the nitride layer with light. The forming the nitride layer includes leaving a cavity in a space inside a depression of the unevenness while forming a thin film on the depression. The film includes a same material as part of the nitride layer. The separating includes causing the film to absorb part of the light so that intensity of the light applied to a portion of the nitride layer facing the depression is made lower than intensity of the light applied to a portion facing a protrusion of the unevenness.

    摘要: A fixing device includes a fixing rotary body, an opposed member opposing the fixing rotary body to form a nipping portion, and a heater to heat the fixing rotary body. The heater includes heat generators arranged in a width direction of a recording medium and separately supplied with power. When an unfixed image on the medium has an image area and a non-image area, power supplied to each of the heat generators is controlled so that, of the heat generators, a first heat generator corresponding to the image area becomes a higher temperature and second heat generators corresponding to the non-image area becomes a lower temperature. When the second heat generators are adjacent to each other, power supplied to one of the second heat generators closer to the image area is set to be greater than power supplied to another of the second heat generators farther from the image area.
