Phenothiazine is the preferred polymerization inhibitor.
专利号:US-4978806-A 优先权日:1989-01-24 标题:Scale-up and synthesis of 1-methoxycyglohepta-1,3,5-triene 发明人:LANGFORD GORDON E 权利人:UNITED KINGDOM GOVERNMENT 摘要:A method for preparation of 1-methoxycyclohepta-1,3,5-triene in commercial quantities, which comprises the steps of heating 7,7-dichloro-1-methoxybicyclo[4.1.0]heptane in a refluxing reaction solvent comprising a lower boiling aromatic amine, at reflux, until suitable amounts of 1-methoxycyclohepta-1,3,5-triene have been produced, and recovering the 1-methoxycyclohepta-1,3,5-triene. Suitable reaction solvents include 2-picoline, pyridine and 2,6-lutidine. The method according to the present invention results in safer temperature control in the production of 1-methoxycyclohepta-1,3,5-triene, and increased yields.
