Abstract: Disclosed are compounds having a straight or branched aliphatic hydrocarbon structure of formula I: ##STR1## In formula I, n is an integer from one to four and m is an integer from four to twenty. Independently, R.sub.1 and R.sub.2 are hydrogen, a straight or branched chain alkyl, alkenyl or alkynyl of up to twenty carbon atoms in length or --(CH.sub.2).sub.w R.sub.5. If R.sub.1 or R.sub.2 is --(CH.sub.2).sub.w R.sub.5, w may be an integer from one to twenty and R.sub.5 may be an hydroxyl, halo, C.sub.1-8 alkoxyl group or a substituted or unsubstituted carbocycle or heterocycle. Alternatively, R.sub.1 and R.sub.2 may jointly form a substituted or unsubstituted, saturated or unsaturated heterocycle having from four to eight carbon atoms, N being a hetero atom of the resulting heterocyle. R.sub.3 may be either hydrogen or C.sub.1-3. In the compounds, a total sum of carbon atoms comprising R.sub.1 or R.sub.2, (CH.sub.2).sub.n and (CH.sub.2).sub.m does not exceed forty. R.sub.

Abstract: A 5% strength by weight to saturated aqueous solution of N-(2-sulfatoethyl)piperazine sulfate, having a pH of between 4 and 0, can be used to modify fiber material.

Abstract: A method of treatment for atherosclerosis and/or reducing cholesterol using an angiotensin II antagonist. This method of treatment can be used in conjunction with the treatment of hypertension. Substituted imidazoles such as ##STR1## are useful as angiotensin II receptor antagonists for this method of treatment. A method of treatment for atherosclerosis and/or reducing cholesterol using an angiotensin II receptor antagonist in combination with an HMG-Co A reductase inhibitor. A method of treatment for atherosclerosis and/or reducing cholesterol using an angiotensin II receptor antagonist in combination with an HMG-Co A reductase inhibitor and an angiotensin converting enzyme inhibitor. Also within the scope of this invention are pharmaceutical compositions for this method of use.

Abstract: Angiotensin converting enzyme inhibitors have the formula Z(CH.sub.2).sub.n CHR.sub.1 COOCHR.sub.2 COOHin which Z is --SR.sub.3, --COCHR.sub.4 NHCOR.sub.5, ##STR1## or --NHCHR.sub.7 COOH, R.sub.4, R.sub.5, R.sub.6, and R.sub.7, which may be the same or different, are each phenyl or alkylphenyl C.sub.7-12,R.sub.4 is hydrogen, alkyl C.sub.1-6, NHR.sub.8 or (CH.sub.2).sub.p R.sub.9,R.sub.2 is (CH.sub.2).sub.m XR.sub.10, alkyl C.sub.1-6 optionally substituted by a saturated 5- or 6-membered carbocyclic or heterocyclic ring, alkylhalo C.sub.1-6, alkylcyano C.sub.1-6, or alkyl phenyl C.sub.7-12, the phenyl being optionally substituted by NO.sub.2 or NH.sub.2,X is O, S(O).sub.q, C.dbd.O or NR.sub.11, andR.sub.10 is alkyl C.sub.1-6, alkylhalo C.sub.1-6, alkoxy C.sub.1-6, alkoxy C.sub.1-6 substituted by halogen, alkanoyl C.sub.1-6, S(O).sub.r R.sub.12, NR.sub.13 R.sub.14, phenyl, alkylphenyl C.sub.

Abstract: A silver salt solution suitable for depositing silver on a support in the preparation of silver catalysts is made by reacting a silver compound with a neo-acid, in a hydrocarbon solvent. The reaction is completed under reflux conditions, thereby removing water formed by the reaction and reacting at least 90% of the unreacted acid. Therefore, the solution may be used without further processing to impregnate a porous support, thereby providing a catalyst useful for oxidation of ethylene oxide.
