  • Process for preparing alkyl (meth)acrylates
    Patent number: 6506930
    Abstract: A process for preparing alkyl acrylates is disclosed. The process provides for the synthesis of alkyl (meth)acrylates, hydrolysis of process impurities into starting materials and separation of starting materials and reaction products in one reactor.
    Type: Grant
    Filed: October 13, 1999
    Date of Patent: January 14, 2003
    Assignee: Rohm and Haas Company
    Inventors: Jeremia Jesaja Venter, Mario Giuseppe Luciano Mirabelli
  • Process for producing butyl acrylate
    Patent number: 6180819
    Abstract: An improved process for producing n-butyl acrylate in high yield and high purity substantially free of acrylic acid, incorporates one or more of the following new process components in an acid-catalyzed esterification process for producing n-butyl acrylate: 1. A hydrolytic recovery component, wherein heavy end adducts produced during the acid-catalyzed esterification are hydrolyzed, recovered, and recycled as valuable reactants from a hydrolytic recovery unit (HRU); 2. A cracking reactor component, preferably used with the HRU, wherein additional valuable reactants are recovered and recycled after treatment in the cracking reactor; and 3. A new distillative component, wherein a crude n-butyl acrylate stream is efficiently distilled in an aqueous mode through an acrylic acid separation column, thereby providing n-butyl acrylate substantially free of acrylic acid and in high yield. The first two components also are applicable to acid-catalyzed processes producing C1 to C4 alkyl acrylates.
