In recent years, inorganic nanoparticles have been widely studied due to the excellent properties that they provide, due to their large surface area, emphasizing applications such as optical, catalytic, electrical, sensing, transport, magnetic, thermal conductivity, electromagnetic. Another methodology in which microwave irradiation was used in the amidation reaction has proven to be an efficient synthesis of amides [15, 16, 17, 18]. Then, copy and paste the text into your bibliography or works cited list. Yasa et al., reported the synthesis and characterization of polyol esters from iso-undecenoic and iso-undecanoic acids, using montmorillonite K10 clay as a catalyst, in presence of deionized water at a temperature of 250°C in an autoclave. In some such compounds, the hydrogen atom in the carboxyl group is replaced with some metal cation . The taking of full-strength carbolic acid orally causes acute gastroenteritis (inflammation of the stomach and intestines), which leads to vomiting, collapse and death. There are also various methods that can be used for the preparation of Carboxylic acids. Physical methods include electrochemical methods, laser ablation, thermolysis, microwave irradiation, and sonochemistry. The beverage industry (juices and drinks) is one of the most controlled and regulated industries in terms of composition and authenticity of products. Licensee IntechOpen. Required fields are marked *. Many reports suggested that organic acids have participated in soil formation, surface weathering, subsurface porosity generation, and ore formation. As well, carboxylic acids can be used in organocatalytic reactions. Since organic acids are intermediate metabolites of all major groups of organic cellular components, it has been repeatedly proven that their presence in excess in various fluids of the human body is linked to the manifestation of certain diseases. For example, the ester ethyl acetate is a very good solvent and is a major component in nail polish remover. A Dictionary of Biology. The first report by this methodology was an esterification reaction with carboxylic acids and alcohols obtaining high yields in a short reaction time [6]. Carboxylic acids and their derivatives are used in the production of polymers, biopolymers, coatings, adhesives, and pharmaceutical drugs. https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/carboxylic-acids, "Carboxylic acids The carboxylic acid compounds still may find applications that cannot be fully covered in this chapter. Many carboxylic acids dissolve in water . All reflexes essentially tamp down until the brain and spinal cord are utterly depressed and coma ensues. Qu et al. Several studies on the inhibitory effect of various organic acids (oxalic, citric, and malic acids) on polyphenol oxidase (PPO), the enzyme responsible for the browning of damaged fruits and vegetables, have been conducted over the years. By Georgiana Ileana Badea and Gabriel Lucian Radu, Submitted: March 12th 2018Reviewed: April 5th 2018Published: June 13th 2018, Home > Books > Carboxylic Acid - Key Role in Life Sciences, *Address all correspondence to: truicageorgiana@yahoo.com, Carboxylic Acid - Key Role in Life Sciences, Edited by Georgiana Ileana Badea and Gabriel Lucian Radu. 16 Oct. 2020 . The urinary organic acid pattern yielded from these metabolic abnormalities is essential for diagnosis. . Examples include formic acid, which is produced by some ants and causes their bites to sting. There are several types of surface modification such as chemical treatments, synthetic polymer grafts, the ligand exchange technique, among others; modification by chemical treatments may include reactions with metal alkoxides, carboxylic acid epoxides, silane coupling agents, among others; this being a convenient method to avoid the agglomeration of the nanoparticles and thus improve the dispersion [51], to achieve the surface modification of nanoparticles has been used ultrasonic irradiation as a technique that obeys the principles of green chemistry, because it reduces the use of solvents as well as energy. PubChem8762. A form of vitamin C is called ascorbic acid and is a carboxylic acid. Consult your pharmacist or local waste disposal company for more details about how to safely discard your product. A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH) attached to an R-group. In Canada - Call your doctor for medical advice about side effects. Nanoparticles with a hydrophilic behavior can be dispersed in polar solvents by modifying them with anionic or cationic polymeric dispersants.
