    摘要： THIS INVENTION PROVIDES COMPOUNDS DERIVED FROM PLICATIC ACID, PARTICULARLY PLICATIN TETRA-ACETATE, AND A PROCESS FOR PRODUCING THEM. THE PROCESS COMPRISES THE ACETYLATION OF SODIUM OR POTASSIUM PLICATATE WITH ACETIC ACID AND PYRIDINE UNDER ANYDROUS CONDITIONS AT AMBIENT TEMPERATURES, PREFERABLY AT 10* TO 40*C. TO PRODUCE PLICATIN TETRAACETATE, INDICATED BY ANALYSES AS (C28H28O13.H2O), IN GOOD YIELD. THE INVENTION ALSO PRODUCES A BY-PRODUCT COMPOUND CLOSELY RESEMBLING PLICATIN TETRA-ACETATE INDICATED BY ANALYSES AS (C30H32O15), PLICATIN TETRA-ACETATE IS USEFUL AS AN INTERMEDIATE FOR FORMING OTHER COMPOUNDS OR PRODUCTS SUCH AS PAINT PIGMENTS AND DYES, AND AS A PLASTICIZER AND STABILIZER FOR PLASTIC SUCH AS CELLULOS ACETIATE, POLYESTERS, VINYL RESINS AND SIMILAR PRODUCTS.

    摘要： A NEW COMPOSITION OF MATTER COMPRISING 1-(3'',4''-DIHYDROXY-5''-METHOXYPHENYL) - 2,(-DIHYDROXY-3-METHYL-6-METHOXY-NAPHTHALENE ("PLICATENOL") HAVING UTILITY AS AN ANTIOXIDANT FOR FATS AND OILS IS DISCLOSED. THIS COMPOUND IS PREPARED BY HEATING PLICATIN (A DERIVATIVE OF PLIACATIC ACID) TO A TEMPERATURE OF ABOUT 200*C. IN THE ABSENCE OF AIR FOR A SUFFICIENT PERIOD OF TIME TO PRODUCE A PYROLYSIS REACTION PRODUCT COMPRISING PLICATENOL.

    摘要： THE UNIFORM ELECTROYLTIC DEPOSITIONOF LEAD FROM A CONVENTIONAL ELEXTROEFINING AQUEOUS ELECTROYLTICSOLUTION CONTAINING LEAD FLUOSILICATE AND HYDROFLUOSILICIC ACID IS PROMOTED BY ADDING TO THE ELECTROLYTIC SOLUTION FROM ABOUT 140-1200 MG./LITER OF A LIGNOSULFONATE AND FROM ABOUT 40-600 MG./LITER OF A WATER-SOLUBLE BLOCK COPOLYMER OF PROPYLENE OXIDE AND ETHYLENE OXIDE HAVING THE FOLLOWING GENERAL FORMULA:

    HO-(CH2-CH2-O)Y-(CH(-CH3)-CH2-O)X-(CH2-CH2-O)Z-H

    IN WHICH X IS AT LEAST 13, AND Y AND Z ARE SUCH THAT THE ETHENOXY CONTENT REPRESENTS FROM 20% TO 90% OF THE COPOLYMER.
