  • Publication number: 20220193611
    Abstract: The invention provides an improvement in terms of control and process technology for a method of continuous removal of a component from a liquid mixture using a membrane unit comprising at least one membrane stage. The improvement is that a portion of the overall permeate stream is recycled to the feed vessel and/or beyond the feed vessel but upstream of the conveying device, and the remainder of the overall permeate stream is removed, with the recycled permeate having a higher concentration of the component to be separated off than the removed permeate. The presently disclosed method can especially be used for separation of a homogeneously dissolved catalyst from a liquid reaction mixture.

  • Publication number: 20220195325
    Abstract: Polyalkyl(meth)acrylates contain specified amounts of long-chain alkyl (meth)acrylates and functional monomers. Lubricant compositions can contain such polyalkyl(meth)acrylates, and the polyalkyl(meth)acrylates can be used as viscosity index (VI) improvers with good fuel economy as well as soot-dispersant function. The polyalkyl(meth)acrylates can provide equal or even unproved deposits in lubricant compositions, especially in engine oil (EO) compositions.

  • Patent number: 11365171
    Abstract: The invention relates to a process for preparing an ester by alkoxycarbonylation of a C2 to C20 hydrocarbon having at least one multiple bond, preferably having at least one olefinic double bond, in which the homogeneous catalyst system used is separated from the product mixture by means of membrane separation and recycled into the reaction zone. In a development of the present invention, the ester thus formed is converted into another ester by transesterification.
