  • Ketene Reactions. I. the Addition of Acid Chlorides
    KETENE REACTIONS. I. THE ADDITION OF ACID CHLORIDES TO DIMETHYLKETENE. II. THE CYCLOADDITION OF KETENES TO CARBONYL COMPOUNDS APPROVED: Graduate Committee: Major Professor Committee Member.rr^- Committee Member Committee Member Director of the Department of Chemistry Dean' of the Graduate School Smith, Larry, Ketene Reactions. I. The Addition of Acid Chlorides to DimethyIketene. II. The Cycloaddition of Ketenes to Carbonvl Compounds. Doctor of Philosophy (Chemistry), December, 1970, 63 pp., 3 tables, bibliography, 62 titles. Part I describes the addition of several acid chlorides to dimethylketene. The resulting 3-ketoacid chlorides were isolated and characterized. The reactivities of acid chlorides were found to parallel the parent acid pKa's. A reactivity order of ketenes toward acid chlorides was established. Dimethylketene is more reactive than ketene which is more reactive than diphenylketene. Attempts to effect the addition of an acid halide to a ketene produced by in situ dehydro- halogenation yielded a-halovinyl esters. The addition of acid chlorides to ketenes was concluded to be an ionic process dependent upon the nucleophilic character of the ketene oc- carbon and the polarity of the carbon-chlorine bond in the acid chloride. Part II describes the cycloaddition of several aldo- ketenes to chloral. The ketenes were generated in situ by dehydrohalogenation and dehalogenation of appropriately substituted acyl halides. Both cis- and trans-4-trichloro- Miyl-2-oxetanones are produced in the cycloadditions with the sterically hindered cis isomer predominating. Isomer distributions were determined by vpc or nmr analysis of the reaction solutions. Production of the ketenes by dehalo- genation resulted in enhanced reactivity of the carbonyl compounds.

  • (VOC) and Organophosphate Flame Retardants (OPFR) in Building Materials
    Identification of volatile organic compounds (VOC) and organophosphate flame retardants (OPFR) in building materials Daniel Duberg 2017-05-29 Exam project, 15 HP, Chemistry Supervisor: Thanh Wang, Josefin Persson Examiner: Tuulia Hyötyläinen Abstract Humans today spend most of their time in various indoor settings such as housing, schools and workplaces. The quality of the indoor environment is therefore of great significance for our wellbeing. However, it has been suggested that the indoor environment contains over 6000 organic compounds, such as various volatile organic compounds (VOC). Around 500 of these compounds is believed to be due to emissions from different surrounding building materials such as insulation, plastic film, sealants and flooring. This study targeted building materials from three low energy preschools that were sampled and analyzed for emissions of VOCs and nine different organophosphate flame retardant compounds (OPFR) using a gas chromatograph coupled to a mass spectrometer (GC/MS). Low energy buildings are buildings that is particularly air tight to be so energy efficient as possible. The study uses a qualitative approach and therefore mainly identifies possible contribution from building materials to indoor environment. More than 100 different VOCs was identified and the most noticeable were meta-, ortho- and para-xylene, toluene, n-hexane and propylene glycol, all but the last compound is associated with hazardous health effects. The building materials that emitted the largest amounts of VOCs was sealants and adhesives. Linoleum flooring and acrylic was also large emitters. Tris(1-chloro-2-propyl) phosphate (TCIPP) were identified in all samples and all nine targeted OPFR compounds were identified in the various material samples and dust samples.
