- The cleaning agent composition and surfactant mixture
-
PROBLEM TO BE SOLVED: To provide a detergent composition which is low irritative to skins, is excellent in the quantity of bubbles in a highly diluted region, and give fine bubbles. ?SOLUTION: This surfactant mixture is a mixture of monoalkyl phosphates represented by the general formula (I) (R is a 8 to 18C straight chain alkyl or alkenyl; X and Y are each H, an alkyl metal, ammonium or an alkanol ammonium, wherein X and Y are simultaneously not H), wherein the contents of the ester salt [the carbon numbers of R in the general formula (I) are 8 to 10, 12, 14, 16, and 18] are 0 to 10 mass%, 50 to 80 mass%, 5 to 20 mass%, 5 to 15 mass%, and 0 to 8 mass%, respectively, and the detergent comprises the surfactant mixture. ?COPYRIGHT: (C)2008,JPO&INPIT ?

- Heterocalixarenes. Part 4 - Synthesis of oxocalix[1]heterocycle[2]-arenes: A unique H-bonding network in calix[1]benzimidazol-2-one[2]arene·1/2 H2O
-
The Friedel-Crafts aroylation of 2-methylanisole with 3-methylbenzoyl chloride followed by NBS bromination and cyclizations with 1,3-dihydrobenzimidazol-2-one, 1,3-dihydro-5,6-dinitrobenzimidazol-2-one, uracil, 6-methyluracil and quinazoline-2,4(1H, 3H)-dione provide respective oxocalix[1]heterocycle[2]arenes 5-9. The X-ray crystal structure (solid) and 1H NMR spectral (solution) studies show them to have by and large inwardly flattened partial cone conformations which vary in torsion angles between the rings. The calix[1]benzimidazol-2-one[2]arene·1/2 H2O complex shows a unique array of H-bonds in which three of the four CH and the imide oxygen of the benzimidazol-2-one unit, carbonyl oxygen and water molecule are involved in H-bonding with surrounding calixarene molecules. This heterocalixarene, in contrast to earlier reported benzimidazol-2-one-based calixarenes, does not show hetero-cyclic π-π stacking.
