Abstract: The present invention relates to a pharmaceutical composition for use in preventing or treating heart diseases in a mammal, which comprises at least one aminoalkanesulfonic acid derivative of the formula (I): ##STR1## wherein X is hydrogen or an amino acid residue; Y is hydrogen, a phenyl group or an alkyl group, which may have a hydroxy, amino, carboxy, phenyl or hydroxyphenyl group; or X and Y are joined to form a trimethylene or hydroxytrimethylene group; and at least one of X and Y is other than hydrogen;or pharmaceutically acceptable salt thereof.

Abstract: The present invention is a process for producing organic esters wherein a dialkyl ether and a carboxylic acid are reacted in the presence of a solid phase acidic catalyst having an acidity factor of at least 0.30, preferably at least 1, under reaction conditions sufficient to form a reaction mixture comprising the desired organic ester and an alcohol and recovering the organic ester. For example, methyl acetate can be prepared by reacting dimethyl ether and acetic acid in the presence of montmorillonite, amorphous silica-alumina or .kappa.-alumina under conditions sufficient to form methyl acetate. While typical processes produce an azeotropic mixture of the desired organic ester and water, the claimed process utilizes a combination or reactants and catalysts wherein water is not produced in appreciable amounts. Therefore, the organic ester product can be separated conveniently thereby avoiding a cumbersome azeotropic distillation step as required in prior art processes.

Abstract: There is provided a process for producing sulfoalkyl-substituted hydroxylamines useful as preservatives to be added to a color developer for photosensitive materials. In this process, the sulfoalkyl-substituted hydroxylamines can be easily synthesized by reacting a specified alkylating agent, cyclic sulfonic ester, vinylsulfonic acid or sulfoalkyl-substituted acrylamide with a hydroxylamine.
