专利号:US-6387238-B1 优先权日:1999-08-05 标题:Electrolytic synthesis of peracetic acid 发明人:MERK TOM L; MALCHESKY PAUL S; LIU CHUNG-CHIUN 权利人:STERIS INC 摘要:An electrolysis unit (10, 210, 310) has an anode (16, 216,316) and a gas diffusion cathode (18, 218, 318). Air is fed to the cathode (18, 218) to generate peroxide species, such as hydrogen peroxide, peroxide ions, or peroxide radicals by electrolysis of oxygenated water. A peracetic acid precursor, such as acetyl salicylic acid, reacts with the peroxide to form peracetic acid. An ion selective barrier (20, 220) optionally separates the unit into two chambers, an anodic chamber (12, 212) and a cathodic chamber (14, 214). By selecting either a proton permeable membrane or an anion exchange membrane for the barrier, the peracetic acid may be formed in either an alkaline electrolyte in the cathodic chamber or in an acid electrolyte in the anode chamber, respectively.
专利号:US-2003072716-A1 优先权日:2001-06-22 标 题:Renewable, carbohydrate based CO2-philes 发明人:POOVATHINTHODIYIL RAVEENDRAN; WALLEN SCOTT L 摘要:A composition is disclosed comprising a carbohydrate-based material a dispersed in carbon dioxide. A general method for synthesizing inexpensive, renewable, non-toxic, non-fluorous, carbohydrate based CO 2 -philes is disclosed. These CO 2 -philes are soluble in carbon dioxide. Methods of making the composition are also disclosed. The methods and composition are useful in a variety of applications and can utilize gaseous, liquid and supercritical carbon dioxide. The methods and compositions are useful in the synthesis of surfactants and metal chelates for CO 2 , as a sizing substrate, in CO 2 -based coating processes, for impregnation and plasticizing cellulosic and non-cellulosic materials, in pharmaceutical applications, such as crystallization, dispersion and encapsulation of bioactive molecules in solid systems, in the densification of CO 2 , in the synthesis of biodegradable polymers in CO 2 , and for carbon dioxide removal, to name just a few.
