    摘要: Disclosed is a process for the preparation of aryl-substituted propionic acid esters having the formula: ##STR1## wherein R and R.sup.1 are a C.sub.1 -C.sub.12 linear or branched alkyl, a C.sub.5 -C.sub.12 cycloalkyl, a C.sub.6 -C.sub.12 aryl or a C.sub.7 -C.sub.12 alkaryl or aralkyl, R.sup.2 is hydrogen or a C.sub.1 -C.sub.20 linear or branched alkyl and R.sup.3 is a C.sub.1 -C.sub.20 linear or branched alkyl, a C.sub.5 -C.sub.12 cycloalkyl, a C.sub.6 -C.sub.12 aryl or a C.sub.7 -C.sub.20 alkaryl or aralkyl, and may be the same or different, or R.sup.1 is hydrogen, which comprises forming a reaction mixture of a phenol, at least one base catalyst and an acrylate, in the presence of 1,2-dimethoxybenzene, wherein the acrylate is added at once or over a period of time from 5 to 60 minutes at atmospheric pressure. The process results in excellent yields of the desired product with good rates of conversion.

    摘要: Materials such as amines, alcohols, aminoalcohols, ethers and mixtures thereof, including halogenated adducts thereof, have been found to be useful floc modifiers for water clarifiers to form an effective overall water clarifier composition. The water clarifier portion of the composition is a dithiocarbamate. The floc modifier of a particular water clarifier composition need not be the same compound that is reacted with carbon disulfide (CS.sub.2) to make the water clarifier portion of the novel compositions.

    摘要: An aminosilane of the formula: ##STR1## where R.sub.1 is a linear or branched C.sub.1-22 alkyl or C.sub.3-22 cycloalkyl, which may be substituted with at least one halogen atom; R.sub.2 is a bis(linear or branched C.sub.1-22 alkyl or C.sub.3-22 cycloalkyl)amino, a substituted piperidinyl, a substituted pyrrolidinyl, decahydroquinolinyl, 1,2,3,4-tetrahydroquinolinyl or 1,2,3,4-tetrahydroisoquinolinyl, with the substituent selected from the group consisting of C.sub.1-8 alkyl, pheny. C.sub.1-8 linear or branched alkylsubstituted phenyl and trimethylsilyl, with the proviso that when the substituent is C.sub.1-8 alkyl, there must be at least two such substituent groups present and R.sub.1 must contain halogen; and R.sub.3 is a linear or branched C.sub.1-8 alkyl or C.sub.3-8 cycloalkyl. The aminosilane may be reacted with an aluminum-alkyl compound and a solid component comprising a titanium compound having at least one titanium-halogen bond and an electron donor, both supported on an activated anhydrous magnesium dihalide, to form a catalyst for polymerization of olefins.
