Matthew MacLennan presented research on naphthenic acids (NAs) found in oil sands process-affected water. He summarized previous work by Cai using EDC-NHS derivatization followed by CE-MS analysis. MacLennan's own work involved aqueous EDC-Sulfo-NHS derivatization of two OSPW samples followed by tITP-CE-MS, which showed suspect peaks. Future plans include activating NAs with NHS/Sulfo-NHS to make them dry-stable, or doing a Fischer esterification with methanol-HCl for CE-ESI-MS analysis commonly used in lipidomics.
The document summarizes experiments conducted on carboxylic acids and their derivatives. It discusses (1) esterification reactions between acetic acid and ethanol catalyzed by sulfuric acid, (2) using ferric chloride tests to detect phenols and enols, (3) hydrolysis reactions of anhydrides and benzamide producing carboxylic acids and ammonia, and (4) using dicarboxylic acids to remove stains. Key points covered include the mechanisms of esterification and hydrolysis, results of qualitative tests, and observations made during the experiments.
Experiment 15. Reactions of carboxylic acidsAlex Rabanes
This document describes an experiment involving reactions of carboxylic acids. It includes drawing structural formulas of common carboxylic acids, writing equations for reactions like ionization and with NaOH and NaHCO3. Results show trichloroacetic acid is most acidic due to chlorine electron withdrawal. Solubility depends on structure. Carboxylic acids are resistant to oxidation but some can oxidize. Evidence of esterification is change in odor and insolubility in water.
This document provides information about carboxylic acids and carboxylic acid derivatives (esters). It discusses the properties, structures, nomenclature, preparation methods, and reactions of carboxylic acids and esters. Key points include:
- Carboxylic acids contain a carboxyl group consisting of a carbonyl and hydroxyl group attached to the same carbon. They have higher boiling points than similar molecules due to hydrogen bonding.
- Esters are carboxylic acid derivatives where the hydroxyl hydrogen is replaced by an alkyl or aryl group. They have pleasant aromas and are slightly soluble in water.
- Carboxylic acids and esters undergo acid-base reactions, esterification,
The document discusses alkylation, which is the transfer of an alkyl group between molecules. It is used in oil refineries to upgrade petroleum by alkylating iso-butane with olefins. There are three main types of alkylating agents: nucleophilic, electrophilic, and carbenes. In oil refineries, iso-butane is typically alkylated with low molecular weight alkenes using a strong acid catalyst like sulfuric acid or hydrofluoric acid. The alkylation unit increases the octane rating and value of the gasoline produced.
The document summarizes key information about carboxylic acids from their general formula of RCOOH to their characteristic properties and reactions. It discusses (1) the nomenclature and structures of carboxylic acids, (2) their higher boiling points and water solubility compared to similar molecules due to hydrogen bonding, (3) their acidity stemming from ionization of the carboxyl group, and (4) several important reactions including preparation by oxidation, esterification, and formation of derivatives like acid chlorides, anhydrides, salts, and amides.
