3-hydroxy-2,2,4-trimethylpentyl isobutyrate

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A 100 g. portion of each polymer was neutralized to pH=9.5 with ammonia, an additional 0.52 g. of ammonia was added (one equivalent based on acetoacetate) to ensure complete enamine formation. To all three samples was added a premix consisting of 0.32 g. nonionic surfactant (Triton X-405; Union Carbide), 4.4 g. propylene glycol, 4.4 g. coalescent (Texanol) and 1.1 g. a 10% aqueous solution of urethane rheology modifier (QR-708; Rohm and Haas). The formulated mixture was equilibrated for 24 hours and then coatings were applied on glass plates to give 3-4 mil thick coatings. Films were placed outdoors in complete sunlight for 12 days. Film swell ratios in methyl ethyl ketone were obtained. To all three samples was added a premix to give 3-4 mil thick coatings for 12 days

实验步骤: Into a one-liter, four-necked, round bottom flask equipped with stirrer, condenser, and thermometer, 200.0 parts of pyridine and 54.0 parts of 3-hydroxy-2,2,4-trimethylpentyl 2-methylpropionate were mixed under a nitrogen blanket and cooled to 0° C. using an ice water bath. To this, 57.0 parts of para-toluenesulfonyl chloride were added in portions over a thirty minute period. The solution was stirred for one hour at 0° C. and then allowed to stand for twenty-four hours at 15° C. The mixture was subsequently poured into one liter of ice water, which was then extracted with 700 parts of methylene chloride. The organic layer was washed successively with cold 6N sulfuric acid (until the water layer was acidic to pH paper); dilute sodium bicarbonate (three times with 500 part-portions); and water (twice with 500 part-portions). It was then dried over sodium sulfate, filtered, and the solvent removed in vacuo to yield the 1-isobutyryloxy-2,2,4-trimethylpentane-3-yl para-toluenesulfonate.
