Pine oleoresin [1 kg. containing 260 g. (0.86 mole) of levo-pimaric acid] (Notes 1 and 2) is dissolved in 2 1. of acetone in a 4-1. beaker. A solution of 200 g. (2.2 moles) of 2-amino-2-methyl-1-propanol (Note 3) in 200 ml. of acetone is added as rapidly as possible with stirring. The pasty precipitate which forms almost immediately is collected by suction filtration and is pressed as dry as possible using a rubber dam (Note 4). The crude moist precipitate is returned to a 2-1. beaker and is dissolved in the minimum volume ( 1 1.) of boiling methanol. The methanolic solution is cooled to 5° in a refrigerator and stirred occasionally to expedite crystallization. When the crystallization is completed, the solid is collected by suction filtration. The precipitate is redissolved in a minimum volume of boiling methanol ( l 1.) (Note 5), the solution concentrated to two-thirds its original volume (Note 6), cooled to 5°, and the amine salt allowed to... 

The maximum observed rotation for the 2-amino-2-methyl-1-propanol salt of levopimaric acid is [a] n —218°. Methanol and ethanol solutions give the same specific rotations, but methanol is the preferred solvent because the time required to effect solution in ethanol is longer. If pure levopimaric acid, m.p. 151-153°, [a] D —276° is desired, the salt with —210° rotation should be dissolved in 8 parts of boiling methanol, the solution concentrated to the point of incipient crystallization, cooled, and filtered. The yield in this recrystallization is about 70%.

Enteric polymers can be coated from aqueous latexes or from aqueous solutions that are produced by solubilizing the polymer via pH neutralization with the addition of an alkali or organic base. Typical neutralizing agents used to create aqueous solutions of enteric polymers include ammonia sodium hydroxide, triethanolamine 2-amino-2-methyl-1-propanol and ammonium hydrogen carbonate. In most cases acid preireal-ment is required to convert the enteric polymer from its salt state back to the neural state to achieve enteric functionality of the polymer however, it has been reported that acid...
