摘要:Simple and economic electrolytic synthesis of peracetic acid is performed, and cold drink containers, etc., are sterilized/cleaned with an aqueous solution of peracetic acid thus obtained. Peracetic acid is electrolytically synthesized from acetic acid and/or acetate and an oxygen-containing gas as starting materials in the presence of a solid acid catalyst in an electrolytic cell. An object to be cleaned is sterilized/cleaned with an aqueous solution of peracetic acid thus obtained. Peracetic acid can be simply obtained at a reduced cost. The sterilizing/cleaning of an object to be cleaned with peracetic acid can be conducted efficiently.

标 题:Sensitive oligonucleotide synthesis using sulfur-based functions as protecting groups and linkers
发明人：FANG SHIYUE
权利人:FANG SHIYUE
摘要:Embodiments for the synthesis of sensitive oligonucleotides as well as insensitive oligonucleotides are provided. Sulfur-based groups are used for the protection of exo-amino groups of nucleobases, phosphate groups and 2′—OH groups, and as cleavable linker for linking oligonucleotides to a support. Oligonucleotide syntheses are achieved under typical conditions using phosphoramidite chemistry with important modifications. To prevent replacing sulfur-based protecting groups by acyl groups via cap-exchange, special capping agents are used. To retain hydrophobic tag to assist RP HPLC purification, special phosphoramidites are used in the last synthetic cycle. With the sulfur-based groups for protection and linking, oligonucleotide deprotection and cleavage are achieved via oxidation followed by beta-elimination under mild conditions. Therefore, besides for insensitive oligonucleotide synthesis, the embodiments of the invention are capable for the synthesis of oligonucleotide analogs containing sensitive functional groups that cannot survive the harsh conditions used in prior art oligonucleotide synthesis technologies.

摘要:Provided is a method for manufacturing an anode in which an anode effect does not easily occur, even if used when electrolyzing an electrolytic solution containing hydrogen fluoride and a metal fluoride to electrolytically synthesize fluorine gas. The method for manufacturing an anode for electrolytic synthesis of fluorine gas comprises a positive polarization treatment step. In the positive polarization treatment step, an anode base material having a carbon material is immersed as an anode (21) in a mixed liquid (10) for anode production, the mixed liquid (10) containing hydrogen fluoride, a metal fluoride, and potassium hexafluoronickelate(IV) together with immersing a cathode (22) therein, a current is passed between the anode (21) and the cathode (22) to subject the anode base material to a positive polarization treatment, and nickel fluoride is caused to adhere to the surface of the anode base material.

标题:One step synthesis of ultrahigh molecular weight block copolymers
发明人：URBAN MAREK W
权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION
摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.
