摘要:
A compound having a plurality of (meth)acrylate functional groups may be a ((meth)acryloylalkyl)amide. Preferably the compound having a plurality of (meth)acrylate functional groups is derived from a natural oil. More preferably the compound having a plurality of (meth)acrylate functional groups is derived from a metathesized natural oil. A compound having a plurality of (meth)acrylate functional groups may be used in a polymerization reaction. Monomers having a plurality of (meth)acrylate functional groups may be used as chain extenders, as crosslinkers, or as branching points in a polymer. A compound having a plurality of (meth)acrylate functional groups, such as the reaction product of a metathesized natural oil and a bis(aminoalkyl) amine and/or a compound represented by Structure I above, also may be used to form a dendritic molecule.
摘要:
The invention concerns a process for enriching an iron mineral from a silicate containing iron ore by inverse flotation comprising the addition of a collector or collector composition comprising at least one of the compounds of formulae RC(0)N(Z-0-X-NH 2 ) 2 (la); RC(0)N(Z-0-X-NH 2 ) 2 H + Y - (lb); in which X is an aliphatic alkylene group containing 2 to 6 carbon atoms; Z is an aliphatic alkylene group containing 2 to 6 carbon atoms; Y - is an anion; and R is a saturated or unsaturated, linear or branched, aliphatic or aromatic moiety having between 7 and 23 carbon atoms. The invention also relates to the novel compounds according to formulae (la) and (lb), compositions comprising said compounds and the use of compounds and formulations as collectors for enriching of iron mineral.

摘要:
Compounds represented by the following general formula (I), prodrugs thereof, salts thereof and drugs containing the same as the active ingredient: (I) wherein each symbol has the meaning as defined in the specification. Because of having an EDG−1 agonism, the compounds of the general formula (I) are useful in preventing and/or treating arteriosclerosis obliterans, thromboangiitis obliterans, Buerger’s disease, peripheral arterial disease of diabetic neuropathy, sepsis, angiitis, nephritis, pneumonia, brain infarction, myocardial infarction, edematous diseases, arteriosclerosis, hemorrhoid, anal fissure, varicosity such as anal fistula, dissecting aneurysm, angina, DIC, pleuritis, congestive heart failure, multiorgan failure, bedsore, ambustion, ulcerative colitis, Crohn’s disease, heart transplantation, kidney transplantation, skin transplantation, liver transplantation, osteoporosis, pulmonary fibrosis, interstitial pneumonia, chronic hepatitis, cirrhosis, chronic renal failure or glomerular sclerosis.
摘要:
A method for synthesizing enantionmerically enriched chemical intermediates with predetermined chirality is described. The method comprises formation of a pseudoephedrine amide, followed by stereoselective alkylation at the alpha carbon. The chiral auxiliary can then be cleaved off, affording chiral end products useful for further transformations. The enantiomeric enrichment of the chiral end products may exceed 98 %, and the chiral auxiliary can be recovered. Novel amides of pseudoephedrine used in this method are also disclosed.
摘要:
Phenylcarboxylic acid derivatives represented by formula (I), and their salts, wherein R1 and R2 each represents H, halogen, alkyl, haloalkyl, alkanoyl, cycloalkyl, nitro, amino, -O-D-R5 (wherein D represents alkylene, and R5 represents H, amino, morpholino, carboxyl, phthalimido, phenyl or epoxy), substituted or unsubstituted phenoxy, substituted or unsubstituted phenylalkylamino, carboxylalkenyl or, when taken together, represent alkylenedioxy; R3 represents H, -E-R6 (wherein E represents alkylene, and R6 represents H, carboxyl, cyano, OH, phenylalkoxy or halogen-substituted phenyl or phenylcarbamoyl), -CO-G-R7 (wherein G represents alkylene, and R7 represents H or substituted or unsubstituted phenylcarbamoyl), substituted or unsubstituted benzoyl, alkenyl, carbamoyl, phenyl or halophenyl; R4 represents H, alkyl; A represents alkylene, cycloalkyl ring-fuzed alkylene or alkenylene; B represents alkylene or alkenylene; and $(1,3)$ represents 0 or 1.
