摘要:
A method is described for the production of regenerated cellulose membranes which method comprises the steps of:(a) dissolving a cellulose material to form a solution;(b) casting the cellulose solution into a film;(c) coagulating the cellulose solution film using an alkali alcoholic solution;(d) washing the coagulated cellulose film in an alcohol;(e) regenerating the cellulose film using acidic alcohol solution;(f) washing the regenerated cellulose membrane using an alcohol.The regenerated cellulose thus formed may be dried, if desired, preferably without a softener.The regenerated cellulose thus produced, when prepared in the form of a film or membrane, possesses higher flux and superior selectivity for organic liquid separation than regenerated cellulose membranes prepared employing aqueous solutions in steps b through e above and is most advantageously employed for the recovery of polar dewaxing solvents (e.g. ketones and mixed ketone/aromatic solvents) from dewaxed oil.
摘要:
This invention relates to a class of novel phosphonate derivatives of lipophilic amines which exhibit squalene synthase inhibition properties. More specifically the compounds are bis aryl cycloalkylamino and azacycloalkyl phosphonates. Compounds of this invention reduce levels of serum cholesterol in the body without significantly reducing mevalonic metabolite synthesis. This invention relates also to pharmacological compositions and method of treatment for lowering serum cholesterol levels using the compounds of this invention.
摘要:
The compounds of formula I herein exhibit useful pharmacological activity and accordingly are incorporated into pharmaceutical compositions and used in the treatment of patients suffering from certain medical disorders. More specifically, they are inhibitors of the activity of Factor Xa. The present invention is directed to compounds of formula I, compositions containing compounds of formula I, and their use, which are for treating a patient suffering from, or subject to, physiological condition which can be ameliorated by the administration of an inhibitor of the activity of Factor Xa.
