摘要： PURPOSE:To produce a colorless high-purity chromene compound from a chromanol compound. CONSTITUTION:A chromene compound is produced by dehydrating a chromanol compound in the presence of 50-1,000 pts.wt. (based on 100 pts.wt. of the chromanol compound) of an alumina preferably having an acidity (pH) of 3-10.

摘要： PURPOSE:To control salt concentration and simultaneously to find an abnormal phenomenon, such as a blister generated during electrodialysis by using water solution of salt from a salt chamber while circulating it and when cell voltage exceeds the set value, feeding new water solution of salt. CONSTITUTION:Three kinds of membranes, bipolar membranes B, anion exchange membranes A and cation exchange membranes C, are arranged in order between an anode 11 and a cathode 12 to form alkali chambers 13, acid chambers 14 and salt chambers 15. And for water solution of salt similar to water solution of acid and alkali, the salt chambers and a salt tank 24 are connected by a water solution of salt circulating line 25 and while the water solution of salt discharged from the salt chambers 15 is again returned to the salt chambers 15 through the salt tank 24 to circulate it, it is desalted. At that time, cell voltage is measured and when the voltage exceeds the set value new water solution of salt is fed to the water solution of salt circulating line 25 through a water solution of salt feed line 23. Therefore, the concentration of water solution of salt in the salt chamber is always suited for electrodialysis.

摘要： PURPOSE:To obtain immunological agglutination reagent having high detection sensitivity and little non-specific agglutination by obtaining a sensitized carrier by sensitizing an antigen or an antibody to a carrier consisting of non-biological particles and then treating the sensitized carrier in non-polar amino acid solution. CONSTITUTION:A method for fabricating immunologically agglutinated particles comprises steps of obtaining a sensitized carrier by sensitizing an antigen or an antibody to a carrier consisting of non-biological particles and then treating the sensitized carrier in non-polar amino acid solution. To show carriers consisting of non-biological particles as examples, polystyrene latex, kaolin, carbon powder, organic-inorganic compound particle gelatin particle may be named. An antigen is a substance for producing an antibody to induce body fluid immunology or cell immunology, which may be for example protein, glycoprotein, lipid protein, lipid, nucleic acid, etc., wherein an antigen richer in hydrophobic property has a large effect in maintaining sensitivity, reduction in non-specific reaction, prevention of damage of an agglutinated image, etc. An antibody has activity for specifically coupling with an antigen, wherein IgG, IgM, IgA, IgD, IgE may be named.

摘要： PURPOSE:To provide a method capable of enabling operation for a long period without raising cell voltage even in such a system that polyvalent cations are present in electrodialysis using a bipolar membrane. CONSTITUTION:In the case of operating an electrodialitic tank (figure) in which a cation exchange membrane and a bipolar membrane are incorporated between an anode and a cathode, the pH of a brine solution is regulated to 1 or below and the brine solution is electrodialyzed to produce alkali and acid.
