Abstract:
The present invention relates to specialty pulp products produced using bifunctional reagents composed of polymeric chain and end caps. The polymeric chain is preferably a polyalkylene glycol based polymer and the end caps are preferably a cationic quaternary ammonium. The bifunctional reagents are especially useful in making specialty fluff with dual functional properties - easy defiberization and antimicrobial properties. The specialty fluff of the present invention prevents odor by inhibiting bacteria growth and production of organic matters, especially when used in an absorbent article intended for body waste management such as baby diapers and adult incontinence device.

Abstract:
The present invention provides processes for the preparation of a compound of Formula 2 or a salt thereof, wherein R 1 is selected from the group consisting of H, C 1 -C 3 alkyl, and C(0)R 3 ; R 3 is selected from the group consisting of C 1 -C 6 alkyl, C 6 -C 10 aryl and C 7 -C 20 arylalkyl; the carbon atom marked with "*" is racemic, enantiomerically enriched in the (R)-configuration, or enantiomerically enriched in the (S)-configuration. Also provided are intermediate compounds of the processes.
Abstract:
Amphipathic amine-esters derived from anhydropentitols are prepared through a short sequence of synthetic steps. The process is initiated by the esterification of an anhydropentitol with a fatty acid chloride or a lipase enzyme to form anhydropentitol fatty acid esters, preferably leaving at least one free hydroxyl. The free hydroxyl group(s) are then sulfonated, forming sulfonated anhydropentitol fatty acid esters. The sulfonyl moiety on the sulfonated anhydropentitol fatty acid esters are then subject to nucleophilic displacement by a hydrophilic moiety, illustrated by a primary amine such as AEE or AEEA. The synthetic pathway is efficient and affords modest to high yields of target amphiphilic compounds, which are useful at least as surfactants and plasticizer substitutes for petroleum derived compounds.
