Carboxylic esters are prepared by reacting carboxylic acids with low-boiling alcohols by charging the reaction mixture to a 1st distillation column, withdrawing the reaction components carboxylic ester, water and unconverted alcohol as overhead product and charging this overhead product to a 2nd distillation column, from which (a) the overhead product comprises the alcohol or an azeotropic mixture...

The present invention relates to an improved wrapper for a smoking article having a combustible fuel element encircled by an insulating layer and a physically separate aerosol generating means as well as to smoking articles employing such wrappers. The wrapper encircles at least a portion of the insulating layer for the fuel element and comprises a permeable sheet material which during burning of ...

This invention relates to certain aristeromycin/adenosine derivatives which are useful in inhibiting AdoMet-dependent transmethylation and in the treatment of patients afflicted with neoplastic or viral disease states.

A sanitary napkin (10) having side panels (12,13) intended to be folded around the crotch portion of an undergarment (30) includes an adhesive tape tab (14) secured to the apertured film facing of one panel (12) with a free end overlying the opposite panel (13) in the folded configuration.
