| abstract | 1345113 Alanine monomaleates; resolutions thereof; resolving DL-alanine AJINOMOTO CO Inc 16 March 1972 12447/72 Heading C2C The invention comprises DL-, D- and L- alanine monomaleates; and a process for resolving DL-alanine monomaleate by contacting a supersaturated solution thereof with seed crystals of one or both enantiomorphs; in the latter case the seed crystals and grown crystals are separate or separable from one another. Various embodiments are described. The resulting D- or L-alanine monomaleate can be treated (i) with sodium hydroxide and/or disodium maleate to precipitate monosodium maleate; (ii) with calcium hydroxide and/or monocalcium maleate to precipitate hemi and/or monocalcium maleate; (iii) with barium hydroxide to precipitate monobarium maleate; in each case recovering D- or L-alanine; details of these procedures being given. |
