    摘要： An automatic dishwashing composition is provided including a builder; a nonionic surfactant; a poly(glutamic acid); and a dispersant polymer selected from the group consisting of: (a) a non-sulfonated hydrophobic modified polymer, comprising (i) 60 to 98 wt%, based on weight of the non-sulfonated hydrophobic modified polymer, of structural units of formula I, wherein each R1 is independently selected from a hydrogen and a -CH3 group; and (ii) 2 to 40 wt%, based on weight of the non-sulfonated hydrophobic modified polymer, of structural units of formula II, wherein each R2 is independently selected from a -C1-4 alkyl group and wherein each R3 is independently selected from a hydrogen and a methyl group; (b) a sulfonated polymer; (c) an acrylic acid homopolymer; and (d) a mixtures thereof.

    摘要： A process for producing methacrylic acid comprising: a) producing methacrolein from propionaldehyde and formaldehyde; b) producing methacrylic acid in an oxidative reaction from the methacrolein produced in step a) and water. Step b) is performed at a pressure above 1 bar. Step c) is performed in a reactor system in a liquid phase reaction in the presence of a heterogeneous noble metal-containing catalyst, where the reactor system comprises an oxygen-containing gas. An average concentration of methacrolein in step b) is less than 40 wt% based on the total weight of water and methacrolein. The reactor system of step b) has an average ratio of water to methacrolein less than 40:1 based on an average amount of water and methacrolein entering and exiting the system.

    摘要： A process for producing methyl methacrylate is disclosed, the method comprising: a) producing ethylene from ethanol; b) producing propionaldehyde from the ethylene produced in step a); c) producing methacrolein from propionaldehyde produced in step b) and formaldehyde; and d) producing methyl methacrylate in an oxidative esterification reaction from the methacrolein produced in step c) with methanol. Step c) is performed at a pressure above 1 bar. Step d) is performed in a reactor system in a liquid phase reaction in the presence of a heterogeneous noble metal-containing catalyst, wherein the reactor system comprises an oxygen-containing gas. An average concentration of methacrolein in step d) is less than 40 wt% based on the total weight of methanol and methacrolein. The reactor system of step d) has an average ratio of methanol to methacrolein less than 20:1 based on an average amount of methanol and methacrolein entering and exiting the system.
