Title:
PREPARATION OF LIGHT-COLORED METAL SALT OF ROSIN
Document Type and Number:
Japanese Patent JP3902268
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a light-colored metal salt of rosin having excellent various properties by providing a particular stabilized rosin and conducting a salt forming reaction with a particular metal compd. and, at the same time, a stabilization reaction.
SOLUTION: This light-colored metal salt of rosin is prepd. by conducting a salt forming reaction of a purified, stabilized rosin with a metal compd. contg. at least one metal selected from among lithium, sodium, potassium, magnesium, calcium, and zinc and, at the same time, conducting hydrogenation or dehydrogenation. The metal compd. is pref. any one of an acetate, an oxide, and a hydroxide of the above metal.
