Whole Blood Samples

Abstract Each of 65 laboratories analyzed 10 whole-blood samples for erythrocyte protoporphyrin by one or more of several analytical procedures. These procedures were of two types: (a) extraction of protoporphyrin from the erythrocytes into ethyl acetate/acetic acid, re-extraction into hydrochloric acid, and fluorometric measurement; or (b) direct reading in a portable fluorometer (hematofluorometer), with no pretreatment of the blood sample. Interlaboratory correlation was generally poor, especially between laboratories using extraction procedures. Hematofluorometric results intercorrelated better, but they had a low bias as compared to the extraction approach. Nationwide standardization of the test is required to assure satisfactory interlaboratory performance and to identify laboratories whose results are sufficiently accurate to be used for interpretations according to guidelines set forth by the Center for Disease Control for erythrocyte protoporphyrin testing.

In this paper, some chalcone derivatives (C1, C2) were synthesized based on the reaction of equal amount of substituted acetophenone and substituted banzaldehyde in basic medium. Oxazine and thiazine derivatives were prepared from the reaction of chalcones (C1-C2) with urea and thiourea respectively in a basic medium. Pyrazole derivatives were prepared based on the reaction of chalcones with hydrazine mono hydrate or phenyl hydrazine in the presence of glacial acetic acid as a catalyst. The new synthesized compounds were identified using various physical techniques like1 H-NMR and FT-IR spectra.

Doped Polyaniline

The high purity hydrochloric acid-doped polyaniline has been prepared by chemical oxidation. The catalytic properties in the form of solid have been studied in ethyl acetate. The results show that the yield of ethyl acetate reaches 66.8% when the ratio between the amount of volume of acetic acid and ethanol is l: 2 and the amount of polyaniline is equal to0.6g. The yield of ethyl acetate does not increase with increasing the amount of catalyst, but can increase the number of recycling the catalyst.

Abstract N,N´-(3,3´,4,4´-Benzophenonetetracarboxylic)-3,3´,4,4´-diimido-di-Lamino acids (1a-1d) and N,N´-pyromelliticdiimido-di-L-amino acids (2a-2d) are prepared from the reaction of 3,3´,4,4´-benzenetetracarboxylic-3,3´,4,4´- dianhydride or pyromellitic dianhydride with the corresponding L-amino acids in a solution of glacial acetic acid/pyridine (3:2) at refluxing temperature. 4-(4-((4- Hydroxyphenylimino)methyl)benzylidene amino) phenol (3) is prepared from 4- amino phenol and terephthaldialdehyde in refluxing ethanol. Interfacial polycondensation method was used to prepare the corresponding polymers (PEII1-8) in two immiscible solvents (water/dichloromethane). The resulting poly(esterimide- imine)s (PEIIs) having good inherent viscosities (0.13-1.25 dl g-1), optical activity and thermal stabilities is obtained in high yields.

Oxidation Of Benzene

Direct oxidation of benzene to phenol in liquid phase by H2O2peroxide was examined over Ti/ LUS-1 catalyst in methanol and acetic acid as solvents. The maximum yield and selectivity of the phenol produced was obtained in the presence of acetic acid. It can be attributed to the stabilization of H2O2as peroxy acetic acid species in the radical mechanism for this reaction. Acetic acid interacts with hydrogen peroxide over Ti/LUS-1 and produces acetoxy radicals.
