    摘要: The present invention relates to an industrially advantageous process for producing 2-amino-4,6-dichloropyrimidine, which comprises reacting 2-amino-4,6-dihydroxypyrimidine or its salt with phosphorus oxychloride at a temperature of from 50.degree. to 100.degree. C. in the presence of a solvent and an acid removing agent. Further, the yield of 2-amino-4,6-dichloropyrimidine can be improved by hydrolyzing 4,6-dichloro-2-pyrimidinylphosphoramidic dichloride produced as a by-product of the chlorination reaction to form 2-amino-4,6-dichloropyrimidine. The 2-amino-4,6-dichloropyrimidine produced by the process of the present invention is useful as an intermediate for medicines and agricultural chemicals.

    摘要: It is an object of the present invention to easily and inexpensively provide a structure of effectively utilizing a light incident on an invalid area of a solar cell. Moreover, it is another object to improve output characteristics of the solar cell by effectively utilizing the light. The gist of the present invention resides in a solar battery module in which plate-like solar cells are held between a light penetrable sheet member on a light receiving surface side and a sheet member on a back surface side, and internal apertures are filled with a sealing resin, wherein a light diffusion section for diffusely reflecting a light or a light diffusion section of a white color is arranged in an invalid region of each solar cell.
