3-methylbutyl 3,4,5-trihydroxybenzoate

反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A 15 part quantity of lauryl gallate and 5 parts of isoamyl gallate were dissolved in a mixture of 70 parts of diethyl adipate and 30 parts of oleyl alcohol with heating to prepare an oil. The oil was added to 100 parts of 5% aqueous solution having a pH of 5 and containing SCRIPSET 520 (trade name of styrene-maleic anhydride copolymer, product of Monsant Co.) and a small amount of sodium hydroxide, and emulsified to obtain a dispersion of particles 4.0μ in average size. Ten parts of melamine and 25 parts of 37% aqueous solution of formaldehyde were added to 65 parts of water. The mixture was adjusted to a pH of 9 with sodium hydroxide and heated to 80° C. for 15 minutes, whereby a melamine-formaldehyde initial condensate was obtained. The dispersion was added to the condensate and the mixture was stirred for 1 hour at 75° C. to prepare a microcapsule dispersion. with heating to prepare an oil to obtain a dispersion of particles 4.0μ in average size
