Katrangan |
Methyl heptenone（PGï¼ ‰ duwe ambune kaya jeruk, ijo, lan rasa pait sing ngelingake woh pir. Bisa disiyapake saka minyak jeruk bali utawa jeruk kanthi refluxing sajrone 12 jam ing larutan banyu sing ngemot K2C 03, lan distilasi sabanjure fraksi andvacuum; saka eseto aketoacetic lan methylbuten-3-ol-2 withaluminum alkoholate ing reaksi Carroll banjur diikuti karo pirolisis ester. |

Properti Kimia |
Methyl heptenone（PGï¼ ‰ minangka penting ing tengah sintesis terpenoid. Sifat ambu ora enak. Kasedhiya ing alam minangka produk degradasi terpenes. (Z) -and (E) -Tagetone, [3588-18-9], [6752-80-3], minangka komponen utama tagetesoil. Solanone [1937-54-8] lan pseudoionone [141-10-6] yaiku acyclicC13ketones kanthi balung terpenoid. Solanone minangka salah sawijining faktor penentu rasa tembakau, lan pseudoionone minangka penengah ing ionon sintesisof. |
