Abstract: A new catalytic metal supporting resin production method that can streamline the purification process, and an ultrapure water production method that uses the catalytic metal supporting resin production method are provided. The method for producing a resin includes first filling a single vessel with first anion exchange resin that supports a catalytic metal and second anion exchange resin that does not support a catalytic metal and then purifying together first anion exchange resin and second anion exchange resin that fill the vessel. The ultrapure water production method includes reducing the amount of hydrogen peroxide or dissolved oxygen by causing water being treated that contains hydrogen peroxide or dissolved oxygen to come into contact with an ion exchange resin that contains at least the resin and that is produced by the resin production method.

Abstract: Disclosed is a method for treating phenol wastewater. The method includes the following step: adding a hydrophobic phthalocyanine as a catalyst, and H2O2 as an oxidant into the phenol wastewater. The hydrophobic phthalocyanine is obtained by decorating a hydrophobic group on a bacterial cellulose-metal phthalocyanine with a silane coupling agent; the bacterial cellulose-metal phthalocyanine is obtained by mixing a metal phthalocyanine into a bacterial cellulose medium, biologically culturing with an acetic acid bacterium, and then heating and reducing the mixture; and the metal phthalocyanine is nitro-sulfonic metal phthalocyanine.

Abstract: An alpha olefin synthesis process includes (i) subjecting a first normal alpha olefin to hydroformylation in the presence of carbon monoxide and hydrogen to form a first linear aldehyde, (ii) subjecting the first linear aldehyde to decarbonylative olefination to form a linear internal olefin, (iii) subjecting the linear internal olefin to isomerization-hydroformylation in the presence of carbon monoxide and hydrogen to form a second linear aldehyde, and (iv) subjecting the second linear aldehyde to hydrogenation to form a linear alcohol followed by dehydration to form a second normal alpha olefin, or subjecting the second linear aldehyde to combined hydrogenation-dehydration in a single step to form a second normal alpha olefin. Using this process, for example, ethylene can be converted to 1-hexene, and 1-butene can be converted to 1-decene.
