Available in PDF, EPUB and Kindle. Book excerpt: That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food technologists, pharmacologists, taxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.

Werkgroep van Deskundigen ter Vaststelling van MAC-Waarden and published by . This book was released on 1991 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NAEL of 7500 mg MEK/m3 (rat, 90 days) will be taken as a starting point. In view of the absence of long-term data and carcinogenicity data a safety factor of 10 is taken. Therefore, a OEL of 7500 : 10 mg/m3 = 750 mg MEK/m3 TWA 8 hr (250 ppm) is advised for exposure to MEK alone. Since skin absorption can add to the inhalatory exposure a "H" indication is advised. This value is above the odour threshold of detection; Biological monitoring it is advised to use as a BEI 2.7 mg MEK/l urine at the end of the workshift.

Download or read book Conversion of Methyl Ethyl Ketone MEK to Valuable Chemicals Over Multifunctional Supported Catalysts written by Zahraa Fadhil Zuhwar Al-Auda and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work describes the conversion of bio-derived methyl ethyl ketone (MEK) into different useful chemicals. The first part discusses the direct conversion of MEK to butene over supported copper catalysts (Cu-Al2O3, Cu-zeolite Y sodium (Cu-ZYNa) and Cu-zeolite Y hydrogen (Cu-ZYH)) in a fixed bed reactor. In this reaction, MEK is hydrogenated to 2-butanol over metal sites, and further dehydrated on acid sites to produce butene. Experimental results showed that the selectivity of butene was the highest over Cu-ZYNa, and it was improved by finding the optimum reaction temperature, hydrogen pressure and the percentage of copper loaded on ZYNa. The highest selectivity of butene (97.9%) was obtained at 270 °C and 20 wt% Cu-ZYNa. Over Cu-Al2O3, the selectivity of butenes was less than Cu-ZYNa since subsequent hydrogenation of butene occurred to produce butane. It was also observed that with increasing H2/MEK molar ratio, butane selectivity increased. However, when this ratio was decreased, hydrogenation of butene was reduced, but dimerization to C8 alkenes and alkane began to be favored. The main products over 20% Cu-Al2O3 were butene and butane, and the maximum selectivity of butene (87%) was achieved at an H2/MEK molar ratio of five. The lowest selectivity of butene was obtained using Cu-ZYH, reaching ~40%. It was found that the amount of acidity in Cu-ZYH is much higher than in Cu-ZYNa (from (NH3-TPD) measurements). This could have caused the selectivity of butene to decrease as a result of dimerization, oligomerization and cracking reactions. The second part describes the conversion of MEK to higher ketones in one step using a multifunctional catalyst having both aldol condensation (aldolization and dehydration) and hydrogenation properties. 15% Cu supported zirconia (ZrO2) was investigated in the catalytic gas phase reaction of MEK in a fixed bed reactor. The results showed that the main product was 5-methyl-3-heptanone in addition to 5-methyl-3-heptanol and 2-butanol with side products including other heavy products (C12 and up). The effects of temperature and the molar ratio of reactants (H2/MEK) on overall product selectivity were studied. It was found that with increasing temperature, the selectivity to C8 ketone increased, while selectivity to 2-butanol decreased. The hydrogen pressure plays significant role on the selectivity of products. It was observed that with increasing the H2/MEK molar ratio, 2-butanol selectivity increased due to hydrogenation reaction while decreasing this ratio leads to increasing aldol condensation products. In addition, it was noted that both conversion and selectivity to the main product increased using a low loading percentage of copper, 1% Cu-ZrO2. The highest selectivity of 5-methyl-3-heptanone (~63%) was obtained at temperatures around 180 °C and a molar ratio of H2/MEK of 2. Other metals (Ni, Pd and Pt) supported on ZrO2 also produced 5-methyl 3-heptanone as the main product with slight differences in selectivity, suggesting that a hydrogenation catalyst is important for making the C8 ketone, but the exact identity of the metal is less important. The third part discusses the conversion of C8 ketones to C8 alkenes and C8 alkane over a catalyst consisting of a transition metal (Cu or Pt) loaded on alumina (Al2O3). These bifunctional catalysts provide both hydrogenation and dehydration functionalities. The main products over 20% Cu-Al2O3 were a mixture of 5-methyl-3-heptene, 5-methyl-2-heptene and 3-methyl heptane. However, using 1% Pt-Al2O3 the major product was 3-methyl heptane with a selectivity reaching over 97% and a conversion of 99.9 %. Both temperature and the hydrogen pressure play an important role on the conversion of C8 ketone as well as the selectivity of products (C8 alkenes and C8 alkane). Over 20% Cu-Al2O3, it was observed that increasing the reaction temperature led to an increase in the selectivity to C8 alkane as a result of hydrogenation of the C8 alkene. Also, it was observed that with an increase in H2/C8 ketone molar ratio, C8 alkane selectivity increased. However, when this ratio was decreased, the further hydrogenation of C8 alkene to C8 alkane was reduced. The highest selectivity of C8 alkene (81.7%) was obtained at 220 °C and a H2/C8 ketone molar ratio of 2. In addition, an experiment was carried out using a low loading percentage of copper, and it was noted that both conversion and selectivity to the main products decreased over 1% Cu-Al2O3. Over 1% Pt-Al2O3, C8 alkane was the major product with different temperatures indicating that further hydrogenation of C8 alkene was promoted on 1% Pt-Al2O3. At low temperature, for both Cu-Al2O3 and Pt-Al2O3, significant amounts of C8 alcohols are formed because subsequent reactions do not proceed at a fast enough rate. Also using 1% Pt-Al2O3, the main product selectivity is still C8 alkane with all H2/C8 ketone ratios.
