    Abstract: Malonates (I; R1 = H, C1-4 alkyl; R2 = C1-12 alkyl, C3-4 alkenyl, Bz, Ph, cyano; R3 = C1-12 alkyl, C3-4 alkenyl, Bz; X = H, C1-12 alkyl, C3-6 alkenyl, C3-4 alkinyl, C2-21 alkoxyalkyl, C7-11 aralkyl, 2,3-epoxypropyl, C1-4 aliph. acyl), useful as a stabilizer for polymer, were prepd. by the reaction of di-lower alkyl-R2,R3-malonate and 4-piperidinol. Thus, 1 g lithium amide, 188.2 g dimethyldiethylmalonate and 320 g 2,2,6,6-tetramethyl-4-hydroxypiperidine were added in 200 ml tigloin, and reacted in N2 gas at 120oC for 6 hr to give bis-(2,2,6,6-tetramethyl-4-piperidinyl)diethylmalonate.

    AND A REPRESENTS AN OPTIONALLY ALKYL-SUBSTITUTED TETRAMETHYLENE GROUP OR AN OPTIONALLY ALKYL-SUBSTITUTED O,WPHENYLMETHYLENE OR O-W-PHENYLETHYLENE GROUP THE BENZENE RING OF WHICH MAY BE NON-CHROMOGENICALLY SUBSTITUTED, ARE USEFUL AS OPTICAL BRIGHTENERS FOR A GREAT VARIETY OF ORGANIC MATERIALS, E.G. NYLON, POLYETHYLENE GLYCOL TYPE POLYESTER, POLYAMIDE, CELLULOSIC FIBER MATERIALS, AND THE LIKE. A METHOD FOR OPTICALLY BRIGHTENING SUCH ORGANIC MATERIALS, WITH THE AID OF THE NEW COMPOUNDS, AND COMPOSITIONS, ESPECIALLY DETERGENT COMPOSITIONS, CONTAINING THEM HAS OPTICALLY BRIGHTENING INGREDIENTS, ARE ALSO DESCRIBED.
