Hydrogen peroxide/sodium hydroxide

Oxypro (2) A family of pulp-bleaching processes developed by Air Products and Chemicals. Piloted in 1995 at Pittsfield, MA. Oxypro 0R is for processing mixed office waste papers it uses molecular oxygen, optionally hydrogen peroxide, sodium hydroxide, and a stabilizer. First commercialized in Scotland in 1994. [Pg.201]

Tail gas scmbbers are sometimes used on single absorption plants to meet S02 emission requirements, most frequently as an add-on to an existing plant, rather than on a new plant. Ammonia (qv) scrubbing is most popular, but to achieve good economics the ammonia value must be recovered as a usable product, typically ammonium sulfate for fertilizer use. A number of other tail gas scrubbing processes are available, including use of hydrogen peroxide, sodium hydroxide, lime and soda ash. Other tail gas processes include active carbon for wet oxidation of S02, molecular sieve adsorbents (see MoLECULARSIEVEs), and the absorption and subsequent release of S02 from a sodium bisulfite solution.

Directed asymmetric reduction of a ketone has been brought about by the use of an intramolecular homochiral boronate ester250. The latter was readily introduced at a hydroxyl group in the molecule and has allowed the production of the enantiomeric alcohol, from the ketone by use of BH3-complex as the reductant (equation 64). The boronate ester may be readily removed by treatment with hydrogen peroxide-sodium hydroxide, using standard methodology. Other similar reductions have also been reported251-253. [Pg.724]

Hydroboration with borane and various mono- or dialkyl boranes followed by oxidation with hydrogen peroxide/sodium hydroxide leads to an anti-Markovnikov cis hydration of a C —C multiple bond1 2. [Pg.23]

Although water, in some cases, has undergone addition across the C-C double bond in a vinylcyclopropane under acidic, - neutral, " and basic " - aqueous conditions, e.g. formation of 2, the reaction has more often been performed using a two-step procedure. Most frequently used was a one-pot synthesis consisting of hydroboration followed by oxidation with hydrogen peroxide/sodium hydroxide. The alkylboranes, formed in the first step, can be isolated. - The first step has generally been carried out using diborane in tetrahydrofuran 398,410,430,745,852,1025,1590,1609,1793,1833.1877-1884 9-borabi-...

In assessing the potential anti-inflammatory activities of drugs against this type of reaction it must be remembered that a number of non-specific effects reduce the oedema . Thus Lorenz , and Biich and Wagner-Jauregg showed that hydrogen peroxide, sodium hydroxide, kaolin and talc have a nonspecific anti-inflammatory effect when administered intra-peritoneally. These substances suppress oedema produced by egg-white, dextran, 5-hydroxytryptamine and formalin, probably as the result of an obscure reflex mechanism caused by irritation of the tissues at the site of...
