Crystalline carboxylated polypropylene such as Hercoprime G and the car-boxylated amorphous polypropylene such as Epolene E-43 can be used as the base polymer to make polypropylene dispersion (79). To make polypropylene emulsion, the polymer is heated to 170-175°C under 100-120 psig superatom-spheric pressure. Triton X-100, an ethoxylated alkylphenol, or Igepal CO 630, an ethoxylated nonylphenol, can be used as the surfactant. The acid modified polyolefin must be neutralized by a base such as diethyl ethanolamine to maintain the stability of the dispersion. The surfactant is mixed with the molten polyolefin... 

To a stirred — 78 C solution of 5.85 mL (62.5 mmol) of 3-methoxy-l-prnpene in 25 mL of THf- are added 43.1 mL (50 mmol) of 1.16 M. vcc-butyllithium in cyclohexane over a 20-25 min period. The mixture is stirred at — 78 °C for an additional 10 min, and diisopinocampheyl(methoxy)borane [50 mmol prepared from (+ )-a-pinene] in 50 mL of THF is added. This mixture is stirred for 1 h, then 8.17 mL (66.5 mmol) of boron trifluoride diethyl etherate complex are added dropwise to give a solution of diisopiuocampheyl[(Z)-3-inethoxy-2-propenyl]borane. Immediately. 2.8 mL (50 mmol) of acetaldehyde are added and the mixture is stirred for 3 h at — 78 rC and then allowed to warm to r.t. All volatile components are removed in vacuo, then the residue is dissolved in pentane. The insoluble fraction is washed with additional pentane. The combined pentane extracts are cooled to 0 JC and treated with 3.0 mL (50 mmol) of ethanolamine. The mixture is stirred for 2 h at 0rC and is then seeded with a crystal of the diisopinocampheylborane-ethanolaminc complex. The resulting crystals arc filtered and washed with cold pentane. The filtrate is carefully distilled yield 5.6 g (57%) d.r. (synjanti) >99 1 (2/ ,37 )-isomer 90% ee bp 119-120 C/745 Torr.

Cais2b found that phenyllithium can be replaced by other bases, preferably diethyl-amine or ethanolamine. A mixture of cyclopentadiene, tosyl azide, and diethylamine was allowed to stand at 0° for three days then, after addition of water, diazocyclo-pentadiene was extracted with ether (73% yield). The yield is somewhat higher when acetonitrile is used as solvent.2C... 

Bradshaw and Krakowiak have modified the reaction of a dihalide with A-ethyl or A-benzyl-substituted ethanolamine in the presence of a carbonate base in toluene to prepare A,A -diethyl- and A,A -dibenzyldiazapentaeth-ylene glycol in high overall yields (Bradshaw and Krakowiak, 1988 Bradshaw et al., 1988). These diols were reacted with (allyloxy)methyl-substituted ethylene oxide to form the diazahexaethylene glycol containing an (allyl-...

The inclusion of phosphoric acid in the mobile phase increases the potential for error in subsequent quantitation by lipid phosphorus determinations and has been replaced with a mobile phase containing acetonitrile-methanol-sulphuric acid (100 3 0.05) to provide resolution of phosphatidylinositol, phosphatidylserine, phosphatidyl-ethanolamine, phosphatidylcholine, lysophosphatidylcholine and sphingomyelin (Kaduce et al., 1983). The authors reported that a reduction in the sulphuric acid content of the mobile phase caused a broadening of the eluted peaks and an increase in the retention of phosphatidylserine, phosphatidylethanolamine and phosphatidylcholine, while if omitted, these components did not elute. It was also noted that if the methanol content of the mobile phase was increased then the retention times of all the phospholipids were decreased. Samples were therefore injected in chloroform-diethyl ether (1 1) to avoid altering the concentration of methanol in the mobile phase. 

The rates of loss do not correlate with the rates of increase in the hydroxyl index for these systems or with the photoyellowing and uv phenomena. This indicates that the mechanism of oxidation of the amine functionality is complex. An additional feature of interest is the profile of this band loss as related to terminal amine structure. In the simple alkyl substituted systems namely diethyl, dimethyl and dibutyl there is an initial rapid loss followed by a slowing down of the rate of decrease on prolonged irradiation. However, with the oxygen containing systems namely morpholine, N-ethyl ethanolamine and N-methyl ethanolamine the rate of decrease is linear with irradiation time. Evidently, there must be two different mechanisms in operation here. The loss of these infra-red absorption bands may be due to a process of dealkylation via oxidation (see reactions later). The band situated at 2978 cm"l exhibited similar behaviour although the extent of the loss was less than that observed with the previous band and the order of rate loss was marginally different.
