Phenylaceton ist eine farblose bis schwach gelbe Flüssigkeit mit einem starken, charakteristischen Geruch, die in der chemischen und pharmazeutischen Industrie Verwendung findet.

Phenylaceton 4 lässt sich auf unterschiedlichste Art und Weise darstellen. Am wirtschaftlichsten erscheint die Dakin-West-Reaktion von Phenylessigsäure 1 und Essigsäureanhydrid 2 unter Basenkatalyse.

EC Number MDL number MFCD PubChem Substance ID Phenylacetone is the immediate precursor for clandestine production of amphetamine and methamphetamine.

Phenylacetone on anaerobic incubations with rat liver mitochondria gets reduced to phenylisopropanol. Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.

More important for COO: enter a "0" if only two numbers are in front of the letter e. Hydroxyamphetamine was administered orally to five human subjects The lack of effect of administration of neomycin to one patient indicates that the hydroxylation occurs in body tissues.

Unfortunately, at the present time one cannot be completely certain that the hydroxylation of hydroxyamphetamine in vivo is accomplished by the same enzyme which converts dopamine to noradrenaline.

Figure 1. Glycine conjugation of benzoic acid. The glycine conjugation pathway consists of two steps.

First benzoate is ligated to CoASH to form the high-energy benzoyl-CoA thioester. This reaction is catalyzed by the HXM-A and HXM-B medium-chain acid:CoA ligases and requires energy in the form of ATP.

The benzoyl-CoA is then conjugated to glycine by GLYAT to form hippuric acid, releasing CoASH. In addition to the factors listed in the boxes, the levels of ATP, CoASH, and glycine may influence the overall rate of the glycine conjugation pathway.

Drugs or Compounds in Development. When all air had been expelled 0. A vivid reaction took place, the ether refluxed, and a white precipitate was formed lithium salt of the acid.

After the addition of all the methyllithium the precipitate partly dissolved and a weakly opalescent solution was obtained.

If necessary, the solution was then refluxed for minutes to complete the reaction. After the solution had reached room temperature, water was slowly added.

The excess of methyllithium was thus destroyed and lithium hydroxide was formed from the intermediate dilithium salt.

The alkaline water layer, which contained the lithium salt of unreacted acid, was removed in a separatory funnel, and the ethereal layer washed three times with half its volume of water.

The ether solution was then dried over magnesium sulphate, filtered and the ether driven off, first at ordinary pressure and then at aspirator vacuum to give 2.

To a stirred solution of 2-nitropropene 0. Titanium tetrachloride 0. After being stirred for 60 min or when the starting material completely disappears on TLC , water ml was added and the resultant heterogenous mixture was stirred at reflux for 2h.

The organic phase was separated, the aqueous phase extracted with CH 2 Cl 2 , and the pooled organic extracts washed with 1 M Na 2 CO 3 solution and dried over MgSO 4.

After being warmed to ambient temperature min , the yellow solution was diluted with water mL , neutralized with powdered NaHCO 3 and saturated with NaCl.

The 2,4 dinitrophenylhydrazone derivative, recrystallized from methanol, had mp In this preparation, phenylnitropropene is reduced to phenylnitropropane with NaBH 4 in methanol, followed by hydrolysis of the nitro group with hydrogen peroxide and potassium carbonate, a variety of the Nef reaction.

The preparation is a one-pot synthesis, without isolation of the intermediate. This synthesis is not suitable for ring-substituted phenylnitropropenes, as the side chain tends to be oxidized when electron-donating substituents are present on the ring.

Then, with good stirring, 7. The next day, the solution is slowly acidified with 2M HCl with good stirring, care being taken for the evolution of heat and CO 2.

About ml of acid is needed. When the pH of the solution turned acid, the color became significantly more yellow, but the acidity was confirmed with pH paper.

All of the precipitate was also be gone at this point. The solution was extracted with 3xml CH 2 Cl 2 , and the pooled organic extracts washed with ml 2M NaOH and ml H 2 O.

The organic phase was dried over MgSO 4 , filtered with suction, and the solvent removed under vacuum to give a clear yellow oil.

If phenylnitropropene is reduced by iron powder in an acidic medium such as acetic acid or aqueous hydrochloric acid the nitroalkene is reduced to the oxime, which is then hydrolyzed by the acid into the desired phenylpropanone.

Phenylnitropropene 10 g, 61 mmol was dissolved in 75 ml HOAc and slowly dripped into a refluxing slurry of Fe powder 32 g, 0.

The mixture turned brownish and foamy, and the mixture was refluxed on low heat for 1. The reaction mixture was poured into ml water, and was extracted with 3x ml CH 2 Cl 2.

The combined extracts was washed with 2x ml H 2 O and dried over MgSO 4. The top of the condenser was connected to a sulfuric acid trap and this trap was connected to a gas absorption bottle.

The mixture was stirred and heated to refluxing on a steam bath and After refluxing for 5 hours, the solution was practically black.

After cooling to room temperature, the reaction mixture was decomposed by slowly adding water through the condenser, stirring during the addition.

When no more hydrogen chloride was evolved, 20 ml of water and 20 ml of concentrated hydrochloric acid was added. The benzene layer was separated and the aqueous layer extracted with four 25 ml portions of benzene.

All of the benzene solutions were combined and filtered. The benzene was distilled off, and the remaining viscous oil was distilled under reduced pressure.

Even if the method below which uses mercuric chloride is higher yielding than the one using cold sulfuric acid, I would definitely reccommend the one with sulfuric acid, as it is much cheaper to use, Phenylaceton is not disastrous Phenylaceton your health or the environment. Fractional distillation could theoretically be used to separate Phenylaceton, but the size of the column that would have to be used makes that option impractical. Journal Publishers via MeSH. Beta- Hydroxylation. Proceed immediately to next part if at all possible. One piece of lithium with a shining metal surface was rinsed in hexane and transferred into a glass tube with a stopcock and a rubber septum which had been filled with argon. PhenylPropanone from Acetone Enolate If acetone Twin Peaks News reacted with a strong base, which is able to deprotonate one of the relatively acidic alpha protons of the ketone, acetone enolate is formed Inger Stevens quantitative yield.
