发明名称 PROCESS FOR PURIFYING NEOMENTHYLDIPHENYLPHOSPHINE USING METHANOL
摘要 <p>A process for the purification of crude neomenthyldiphenylphosphine, the process comprising crystallizing the crude neomenthyldiphenylphosphine using a solvent consisting essentially of methanol. The process provides for the unexpectedly efficient production of neomenthyldiphenylphosphine having purities of at least 97 mole percent, and more preferably at least about 99 mole percent. Another embodiment of the invention is neomenthyldiphenylphosphine having a purity of at least 97 mole percent produced by crystallizing crude neomenthyldiphenylphosphine having a purity of less than 97 mole percent using a solvent consisting essentially of methanol.</p>
