Patent BR-8807438-A (BR)
Inventor: MATSON STEPHEN L
IPC: C07C309/66
Filed: 1988-03-31
Abstract: This invention relates to novel methods for facilitating the enzymatic resolution of racemic mixtures of esters, which are derivatized with groups which enhance the esters' aqueous solubility, in an extractive member reactor where the enzyme is placed alternatively either (1) in the aqueous phase, (2) in association with the membrane, or (3) in the aqueous phase and in association with the membrane, wherein the aqueous ester phase is contacted with one side of the membrane, and where an organic extractive phase is contacted with the other side of the membrane, wherein the extractive phase serves to remove the resolving reaction product. Of particular significance regarding this invention is its use of water soluble esters that are derivatized with groups which enhance their aqueous solubility and their reactivity with enzymatic resolving methods which are mediated in an aqueous environment. Novel methods were utilized to prepare these esters, for use in this invention's methods for enzymatically resolving the racemic mixtures of the esters, to produce the separate chiral isomers of the racemic mixture. The importance of the resolution of the separate chiral isomers of the racemic mixtures resides in the isolation of the isomers which frequently have different biological activities.

Inventor: MILLER WILLIAM J
IPC: D21C9/10
Filed: 1995-06-29
Abstract: A method for bleaching cellulosic and lignocellulosic pulp using hydrogen peroxide as a bleaching reagent, utilizes a three stage reaction, viz. two short high temperature peroxide bleaching steps (50,160) at a pressure sufficient to suppress boiling and an interstage treatment (90) including a longer atmospheric pressure reduced temperature bleaching step. The two short peroxide bleaching stages include the steps of introducing pulp, at a consistency of 10%-18%, to a mixer (20,130) in which the pulp is heated to a temperature above 100 degree Celsius; adding sufficient sodium hydroxide (32,142) to bring the pulp to a pH of 8.5; adding sufficient hydrogen peroxide (33,143) to equal from about 0.5%-5.0%, by weight, of the pulp; passing the pulp through a pressurized reactor column (50,160) at a rate providing a reaction time in the column of less than 45 minutes, cooling the pulp and discharging the cooled pulp to a washer. It may be desirable to introduce the pulp to a mixer and add alkali to reactivate residual hydrogen peroxide by bringing the pulp to a pH of at least 9 after the first bleaching stage, deposit the pulp in a reaction tower and allowing the reaction to proceed until a substantial portion of the residual hydrogen has been consumed. <IMAGE>
