Table 1 and 2 Table 1. If contacted, remove with plenty of water. In a medium size tube, mix 2mL of benzaldehyde with 15 drops of acetone, and leave it at room temperature for 5 minutes. Then, add the mixture to the ethanol-NaOH solution in small portions and stir with magnetic stirrer if available for 30 minutes. Chill the solution in an ice-water bath. Collect the yellow crystals by suction filtration and hand-dry them by pressing them between dry paper towels. Determine the weight of the dibenzalacetone product, its melting point, and the percent yield. Return the product to your instructor. NOTE- The amounts of the reagents used in this reaction are very important to ensure the correct product forms. In a given example a student added twice as much acetone as the procedure called for. Since there would be such an excess of acetone the benzaldehyde would only see acetone and would not end up adding twice to any acetone molecules. This would give an end product of benzalacetone instead of dibenzalacetone. Structure of dibenzalacetone 8. Answer in space provided. Water-soluble organic solvents are those which serve to wet the pigment and water-soluble inorganic salt, dissolved in water mixed , and is not particularly limited as long as it does not substantially dissolve the inorganic salt used. For example, 2-methoxyethanol, 2-butoxyethanol, 2- isopentyloxy ethanol, 2- hexyloxy ethanol, diethylene glycol, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, triethylene glycol, triethylene glycol monomethyl ether, liquid polyethylene glycol, 1-methoxypropanol, 1-ethoxypropanol, dipropylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, polypropylene glycol of the liquid is used. Water-soluble organic solvent, the total weight of the pigment based parts by weight , preferably used parts by weight, and most preferably used 50 to parts by weight. When salt milling process the pigment, the resin may be added as necessary. The kind of the resin to be used is not particularly limited, it is possible to use natural resins, modified natural resins, synthetic resins, synthetic resins modified with natural resins. Resin used is a solid at room temperature, is preferably water-insoluble, and further preferably partially soluble in the organic solvent.
