实验步骤: To this wrinkle resistant, durable press fabric was applied a treating solution containing 40.0 parts by weight of zinc acetate dihydrate, 125 parts of 30% aqueous hydrogen peroxide, the amount of glacial acetic acid specified in Table IX and 52.8 parts water. The fabric was immersed and thoroughly wet in the treating solution, and was passed through a wringer having squeeze rolls adjusted to give a wet pickup of 105%-120%. The fabric was heat-cured in a forced-draft oven for 5 min. at 85° C., was afterwards washed for 15 min. in hot running water at 60° C., and was oven-dried for 5 min. at 85° C. The zinc and peroxide content, and fabric performance in the parallel streak test with Staphylococcus aureus, are shown in Table IX. to give a wet pickup of 105%-120% was afterwards washed for 15 min. at 60° C. was oven-dried for 5 min. at 85° C

实验步骤: Zinc acetate dihydrate (1.0 g) was dissolved in 75 ml. of hot methanol and 1.4 g of 8-hydroxyquinoline was added to the homogeneous solution. A yellow precipitate formed after a few minutes and the solution was stirred at reflux for 3 hours. The solution was allowed to cool and the precipitate was isolated by filtration and washed with methanol and petroleum ether. After air drying, 1.44 g of bis(8-hydroxyquinolinato)zinc was obtained as a bright yellow solid. A yellow precipitate formed after a few minutes at reflux for 3 hours to cool the precipitate was isolated by filtration washed with methanol and petroleum ether After air drying

实验步骤: Anhydrous L-leucine, 5.2472 g, 0.0400 mole, was dissolved in 30 ml of deionized water and heated to 120° F. Ultra-pure zinc acetate dihydrate, Zn(C2H3O2)2.2H2O, 4.3900 g, 0.0200 mole, was added in small increments over one hour, with stirring. The solution did not clear, so another 20 ml of water was added and the mixture was heated in a boiling water bath to 190° F. for an additional 21/2hours. Water was then added to a total volume of 75 ml, the mixture heated again to 190° F., and gravity filtered. The retained solid was dried at 150° F. for 12 hours, found to weigh 2.717 g, and was analyzed. the mixture was heated in a boiling water bath to 190° F. for an additional 21/2hours the mixture heated again to 190° F. gravity filtered The retained solid was dried at 150° F. for 12 hours
