Nonanoic add

Hexanoic, heptanoic, nonanoic and decanoic adds were the most predominant fatty adds in heated pork fat Nonanoic add was the most abundant Fraction FI for the 207 bar/50°C extract was highly concentrated compared to other fractions.

The first hydrocarboxylation of 1-octene with [PdCl2(PhCN)2] performed in microemulsions of water with SCCO2 showed improved selectivity to the desired adds compared to aqueous/organic biphasic catalysis [33]. This was possible with tris (p-trifluoromethylphenyl) phosphine as well as when fluorinated surfactant was applied. At 90°C and pco = 30bar turnover frequendes 5h were observed. Chemoselectivity to the desired nonanoic add reached 90% with the n/iso ratio varying from 60 40 to 89 11. Isolation of products required extraction with diethyl ether.

Of the fatty adds, nonanoic and decanoic add were the most abundant in the concentrate of fraction FI. Ha and Lindsay (54) postulated that maity of the volatile adds present in beef tallow contributed to the desirable flavor of deep-fiied potatoes. 

Nonanoic acid (pelargonic acid). Equip a 1-litre three-necked flask with a reflux condenser, a sealed stirrer unit and a thermometer. Place 23 g (1 mol) of sodium, cut in small pieces, in the flask, and add 500 ml of anhydrous butan-l-ol (1) in two or three portions follow the experimental details given in Expt 5.95 for the preparation of a solution of sodium ethoxide. When the sodium has reacted completely, allow the solution to cool to 70-80 °C and add 160 g (152 ml, 1 mol) of redistilled diethyl malonate rapidly and with stirring. Heat the solution to 80-90 °C, replace the thermometer with a dropping funnel and add 182.5g (160ml, 1.02mol) of 1-bromoheptane (Expt 5.55) slowly at first until precipitation of sodium bromide commences, and subsequently at such a rate that the butanol refluxes gently. Reflux the mixture until it is neutral to moist litmus (about 1 hour). 

To purify your product, recrystallize your collected solid from acetone. To accomplish this, transfer the solid to a 125-mL flask. Add a small amount (20 ruL to start) of acetone and a stir bar. Heat to fully dissolve the solid. Add small amounts of acetone, order 1 ruL at a time, as needed, to aid in the dissolution. When solid is dissolved, remove from heat. Cool with the aid of an ice bath. Crystals should form. If they do not, try scratching the inside of the flask with a glass rod. Or, boil off some solvent and recool. Remove these crystals by suction filtration just as you did to collect your impure product. Wash these crystals with a cold 5 ruL portion of acetone and allow them to dry on the filter paper. Transfer to a preweighed vial. Calculate yield of cholesteryl nonanoate from cholesterol and calculate the conversion of cholesterol to cholesteryl nonanoate. 

As mentioned above you will be studying mixtures of cholesteryl nonanoate and cholesteryl chloride rather than the pure materials. Mixtures are used for the convenience of working at temperatures closer to room temperature. To prepare a mixture of a given composition, use the mole fraction composition scale. A mole fraction of a component in a mixture is defined as the number of moles of that component in the mixture divided by the total number of moles of all components in the mixture. To actually prepare a mixture, add the desired amounts of each component to a screw cap vial. Mix the components physically with a spatula to make a reasonably uniform mixture of the solids. Place the vial in a sample oven whose temperature has been set to about 100°C and allow the solids to melt and mix. 

A conceptually similar approach was used for producing nanopolymer chains from y-Fe203 NPs. Phase separation between immiscible organic ligands - nonanoic acid and 4-phenylbutyric add - produced two distinct singularities on the surface of the NPs. A subsequent reaction of the molecules...
