Example 5. Glycolysis of Polyurethanes with Propylene Oxide after Pretreatment with Ethanolamine.55 A rigid polyurethane foam (ca. 100 g) was dissolved in 30 g ethanolamine by heating. Excess ethanolamine was stripped, leaving a clear solution. Infrared and GPC analysis indicated that the clear solution obtained contained some residual polyurethane, aromatic polyurea, aliphatic polyols, aromatic amines, and N,N -bis(f -hydroxyethyljurea. Next the mixture was dissolved in 45 g propylene oxide and heated at 120°C in an autoclave for 2 h. The pressure increased to 40 psi and then fell to 30 psi at the end of the 2-h heating period. The product was a brown oil with a hydroxyl number of485. 

The oxidative dehydrogenation of ethanolamine to sodium glycinate in 6.2 M NaOH was investigated using unpromoted and chromia promoted skeletal copper catalysts at 433 K and 0.9 MPa. The reaction was first order in ethanolamine concentration and was independent of caustic concentration, stirrer speed and particle size. Unpromoted skeletal copper lost surface area and activity with repeated cycles but a small amount of chromia (ca. 0.4 wt%) resulted in enhanced activity and stability. 

The oxidative dehydrogenation of ethanolamine over skeletal copper catalysts at temperatures, pressures and catalyst concentrations that are used in industrial processes has been shown to be independent of the agitation rate and catalyst particle size over a range of conditions. A small content of chromia (ca. 0.7 wt %) provided some improvement to catalyst activity and whereas larger amounts provided stability at the expense of activity. 

Figure 2. Effect of Ca-ceramide on phosphatidylcholine and phosphatidylethanolamine synthesis in rat-2 fibroblasts. Cells were treated for 2 h in the absence (open bars) or presence (hatched bars) of 25pM C6-ceramide and the following parameters were determined i) the incorporation of [ H]choline and [ H]ethanolamine into phosphatidylcholine (PC) and phosphatidylethanolamine (PE), respectively (panel A) and in CDP-choline and CDP-ethanolamine, respectively (panel B) and ii) the in vitro activity of choline- and ethanolaminephosphotransferase (CPT and EPT) (panel C).

An example of solid solution formation by separate deposition of binary layers followed by annealing to interdiffuse the two layers is given for Cu3BiS3 deposition [32]. Bi2S3 (film thickness ca. 90 nm) was deposited at room temperature from a Bi(N03)3/triethanolamine/thioacetamide bath onto glass slides. CuS (300-600 nm thick) was then deposited on this film from a CuCli/tri-ethanolamine/ammonia/NaOH/thiourea bath at room temperature. The films were annealed at 250°C for 1 hr. Formation of the CusBiSs phase could be seen from the XRD pattern. Measurement of precipitated powders (prepared by putting the Bi2S3 precipitated in the first deposition in the CuS deposition solution) annealed at 300°C showed more clearly the formation of the solid solution.

Ethanolamine and urea under pressure. A mixture consisting of 60 g. (1 mole) of urea, 61 g. (1.0 mole) of ethanolamine, and 85 g. (5.0 moles) of ammonia was processed in a silver-lined bomb at 300° under a pressure of 930 atm. for 10 min. The product was distilled 12.0 g. of ethanolamine was recovered together with 59 g. of crude ethyleneurea. One recrystallization from chloroform gave 35 g., m.p. ca. 123°. Assuming this product to be 75% pure, the net yield, based upon ethanolamine, was 38%. 

The organic deliquescents tried were ethylene glycol (EG), triethylene glycol (TEG), and mono-ethanolamine (MEA) The experimental runs made adding 5 wt% of EG, TEG, or MEA are presented in Table III. At 75% relative humidity, all three additives slightly decreased the Ca(0H)2 converted after 1 hour of reaction, when compared with the conversion of pure Ca(0H)2 at the same experimental conditions. 

Carboxymethylethanolamine (CME) has been shown to be present in red blood cell membrane hydrolysates at ca 0.14 mmol mol 1 ethanolamine. Carboxymethyllysine was present in the membrane proteins at ca 0.2 mmol mol-1 lysine, in both cases there being no difference between samples from diabetic (free of complications) and nondiabetic subjects.142 CME was also detected in fasting urine at 2-3 nmol mg 1 of creatinine from samples of both diabetic and nondiabetic subjects. Requena et al.142 calculate a value of the 2.8 //mol CME excreted daily, > 99% arising from the normal turnover of membrane lipids of cells other than RBC.
