KONDENSASI ALDOL PDF

Download full text Bahasa Indonesia, 9 pages. Ugm, Pudjono, et al. Benzylidene ketone is a compound in which within the structure there is a benzyl group which is bound to a, 3 unsaturated with ketone. Benzylidene ketone can be synthesized through aldol condensational reaction, using both acid and base catalysts. Condensational reaction of p-nitrobenzaldehyde and cyclohexanone is a multistep condensation so that the formation of the various products was difficult to be avoided. The reaction was done by reacting p-nitrobenzaldehyde and cyclohexanone using hydrochloride acid as a catalyst, being stirred for two hours.

Condensational reaction of p-nitrobenzaldehyde and cyclohexanone is a multistep condensation so that the formation of the various products was difficult to be avoided.

The reaction was done by reacting p-nitrobenzaldehyde and cyclohexanone using hydrochloride acid as a catalyst, being stirred for two hours. The compound formed was the dark yellow powder that had no smell. Spectra UV and JR indicate the differences from the p-nitrobenzaldehyde. The results of the GC-MS interpretation provides information that the compound produced was possibly2-cyclohexylidene 4' - nitrobenzylidene cyclohexanone with the molecular formula of C19H21N03 and the compound 2- 4' -nitrobenzylidene cyclohexanone with the molecular formula of C13H12NO3 and yield of View original from journal.

Kondensasi Aldol

Reaksi aldol adalah salah satu reaksi pembentukan ikatan karbon-karbon yang penting dalam kimia organik. Hal ini dinamakan kondensasi aldol. Reaksi aldol ditemukan secara terpisah oleh Charles-Adolphe Wurtz [7] [8] [9] dan Aleksandr Porfyrevich Borodin pada tahun Borodin mengamati dimerisasi aldol 3-hidroksibutanal dari asetaldehida di bawah kondisi asam. Reaksi aldol digunakan secara meluas pada produksi komoditas kimia berskala besar seperti pentaeritritol [10] dan pada industri farmasi untuk sintesis obat-obatan yang beroptik murni.
