They have excellent applications as solvents and as intermediates for organic synthesis. They are used in the aqueous carrier medium and amide penetrants in inks and water soluble paints.
제조 및 합성 방법
제조 방법
[JACS (1948) vol 70 p 1820] for the synthesis of 1-methyl-4-piperidone: To a one-liter flask containing 350 ml of 20 % hydrochloric acid was added 86 g. of 1-methyl-3-carbethoxy-4-piperidone hyrdrochloride. After refluxing for one hour, the ferric chloride reagent gave no coloration. The solution was evaporated to dryness on a steam-bath at 10 mm. pressure. The solid product, heated at 100 °C for 4 hours at 0.1 mm and further dried over solid KOH for 24 hours, weighed 57.7 g, m.p. 80 - 120 °C.Although this melting range goes above that of the pure comound 0.45 of crude material dissolved in 90 ml. of hot acetone gave 0.40 g of pure compoundd melting at 93 - 95 °C. Other samples of crude piperidone hydrochloride showed even higher melting points than the one mentioned above, yet this apperently impure material always gave good yields of sharp melting product when recrystallized.
