(It is identified as maacid062017rep in the pdf document). The CIR published the Final Report on the Safety Assessment of Malic Acid and Sodium Malate in 2001. Based on the available animal and clinical data available at that time, the Panel concluded that Malic Acid and Sodium Malate are safe for use as pH adjusters in cosmetic formulations; however, the Panel determined that the data were insufficient to determine the safety of these ingredients for any other functions.

  • Effects of Functional Group Interactions on the Gas-Phase Methylation and Dissociation of Acids and Esters
    CORE Metadata, citation and similar papers at core.ac.uk Provided by Elsevier - Publisher Connector Effects of Functional Group Interactions on the Gas-Phase Methylation and Dissociation of Acids and Esters John J. Isbell and Jennifer S. Brodbelt Department of Chemistry and Biochemistry, The University of Texas at Austin, Austin, Texas, USA Functional group interactions have been observed to affect gas-phase ion-molecule chem- istry in a quadrupole ion trap mass spectrometer. Gas-phase methylation and collision- activated dissociation reactions of a series of related acids and esters allows an evaluation of the structural factors that influence reactivity and functional group interactions of these compounds. Examination of the [M + HI+ or [M + 15]+ product ions by collision-activated dissociation has provided insight into the conformations from which diacids and diesters undergo electrophilic addition. Collision-activated dissociation has provided not only more detailed information on the structures of the ions, but also the data necessary for confident mechanistic interpretation. Labeling studies were done to probe fragmentation pathways. Upon activation of the [M + CD,]+ products of dimethyl maleate and dimethyl succinate, formed from reaction of the neutrals with CD,OCD$ ions, a rapid interfunctional group methyl transfer causes scrambling of the methyls prior to elimination of dimethyl ether or methanol. The [M + 151 ’ ions of dimethyl maleate are believed to lose dimethyl ether through a rate-determining 1,6-methyl transfer, whereas the [M + 15]+ ions of dimethyl succinate eliminate methanol through a rate-determining 1,5-proton transfer. (J Am Sot Mass Spectvom 2996, 7, 565-572) unctional group interactions are among the most molecular ion and sizcable losses of H,O and HDO.

    Submitted in partial fulfillment of the requirements for the degree of Master of Science Thermal treatment of drill cuttings Lars Martin Rossi Department of mathematics and natural science University of Stavanger June, 2016 Abstract Increased environmental stringency, and focus on cost efficiency, drives the oil & gas industry towards new and better solutions. Members of OSPAR have to follow strict discharge requirements for oil contaminated drill cuttings, based on the BAT, and BEP principles. The most successful technologies rely on thermal desorption. Only the TCC have received acceptance to treat and discharge OBM cuttings on the NCS, at a require- ment of 0:05 % oil by weight. Norwegian-Group AS is currently developing an integrated treatment solution for drilling fluids, waste water, and cuttings. In this thesis, thermal treatment of cuttings is investigated. The treatment concept rely on dielectric heating with microwaves, in combination with environmentally friendly, polar organic compounds. The initial study shows that glycols can be distilled without significant degradation, especially MEG. In addition to the benefits of increased process temperature, a significant reduction in energy requirement is possible. The energy required to vaporize MEG is in the order of magnitudes lower, than what is required to vaporize water. Due to a higher process temperature , the vapor pressure contribution from the oil was significantly increased. Drill cuttings was successfully treated to well below the OSPAR limit of 1 % oil by weight, by the use of susceptors. The presence of susceptors significantly increased the oil separation from cuttings, especially when the cuttings did not contain water. It is believed that the use of susceptors in combination with microwaves can challenge the TCC technology as BAT.
