    Where did phosphite come from? During WWII, rock phosphate was used as a white phosphorus incendiary and smoke screen. The shortage of rock phosphate concerned ag-officials and they began to look for alternative sources of phosphorus fertilizers. As a result, phosphonates were first considered as fertilizers in Germany and the United States during the 1930s and '40s. Rock phosphate is the beginning of most commercially made phosphorus products in the market today. Without the phosphate, many of our commercially available fertilizers cannot be made such as superphosphate and triple superphosphate. • RP + sulfuric acid = superphosphate • RP + phosphoric acid = Triple superphosphate (TSP) What do all the different terms mean? Phosphoric…

    In the last two weeks, Roundup was added to water and the spectra were measured. The initial test ranging from 1% to 100% was to concentrated. This was indicated because the spectra’s absorbances were larger than one. Furthermore, when looking at figure 1, once above 0.30% data flattens off. Once the range was narrowed with serval more trial the range being now sampled is between 0.01 % to 0.30%. The lambda max is ranging from 307 to 309 wavelengths. Glyphosate’s structure contains three major…

    para-aminobenzoates, cinnamates, benzophenones, dibenzoylmethanes, camphor derivatives and benzimidazoles, absorb the ultraviolet radiations. Oxybenzone is a synthetic estrogen that disrupts the hormonal system when it deeply penetrates the skin. Inorganic ultraviolet chemical filters such as zinc oxide and titanium oxide reflect and scatter the ultraviolet radiation to protect skin. Other ingredients include preservatives (e.g. parabens derivatives), coloring agents (e.g. ammonium sulphate,…

    This experiment worked in the sense that the racemic mixture produced four different products, while the optically pure (R) and (S) only produced one product, or two enantiomers. If the P NMR experiment was performed using the crude reaction mixture of the phosphonate compound without purification then some of the reactants might still be present on the solution and can give different readings since one of the reagents used was phosphorous trichloride. Since enantiomers give of the same peaks in…

    Phosphonates as inhibitors for Pks13-TE Hypothesis for the aim 1 of the proposed project is that the fluorinated α–Aminophosphonates as a covalent irreversible inhibitor for the Mtb Pks13-TE by scission of the P-C bond. Previous studies have shown the fluorinated aminophosphonates (FAPs) demonstrated serine esterases inhibition via scission of the P-C bond as shown in Figure 2.1.A 4. FAPs are known to irreversibly inhibit serine esterases such as acetylcholinesterase16 , neuropathy target…

    and Reese, 1982; Sung, 1982; Huynh-Dinh et al., 1985). Further reaction with triazole gives S.5 (Figure 2.1.3). The purine nucleosides also react with electrophilic reagents. For example, guanine nucleosides react with MSNT to form the corresponding triazolo derivatives. Reaction of the N2-protected guanosine nucleoside S.6 with mesitylene sulfonyl chloride gives the crystalline O6-sulfonated derivative S.7 (Figure 2.1.4; Bridson et al., 1977; Francois et al., 1985). In the presence of pyridine,…

    soil becomes vulnerable to to erosion, causing the soil water carrying capacity to decline. Some factors of soil degradation are deforestation, desertification/ overgrazing, irrigation, improper cultivation, and industrial farming. Chemical degradation is the loss of nutrients and/or organic matter in soil. Some effects of chemical degradation is salinization and acidification. Biological Degradation is the loss of organic matter and biodiversity in soil. It is caused by the usage of…
