HYDROTROPES IN SOAP FLOTATION: A CRITICAL REVIEW
Abstract: In this study efficiency of soap flotation when the hydrotrope was used along with the flotation reagents especially collectors for different type of minerals is reviewed. It is known that for flotation of salt type minerals soaps are used as collectors. The soap collectors when used along with hydrotropes as promoters in flotation yielded better flotation efficiency along with the reduced usage of collectors (soaps). Hydrotropes the compounds that soulibilises …

Hydrotropes as effective reaction Media for the Synthesis of Chlorothiazide
Abstract: The paper describes the synthesis of Chlorothiazide. It is a thiazide diuretic (water pill). It decreases theamount of fluid in the body by increasing the amount of salt and water lost in the urine. It is also used tolower the blood pressure as antihypertensive and to decrease edema (swelling). The synthesis ofChlorothiazide was carried out using four different hydrotropes, the effect of hydrotropes on yield, rateconstant and activation energy at …

A non-hydrotreated feedstock’s polyaromatic cracking under FCC industrial operating conditions using an equilibrium catalyst
Abstract: Catalytic cracking of non-hydrotreated atmospheric residue’s main polyaromatic hydrocarbon (PAHs) in the presence of an equilibrium catalyst was investigated under industrial operating conditions. During the fluid catalytic cracking process, the catalyst that presented the key factor in hydrocarbon cracking (aromatic by hydrogen transfer reaction) quickly deactivated and compromised the process’s performance due to its acid surfaces and pores covered by the polyaromatic species. A deep study of the catalyst behavior …

Sodium Benzoate and Urea as Promoters in Sillimanite Flotation
Abstract: Sillimanite is an alumino-silicate mineral with the chemical formula Al2SiO5. Sillimanite in general is concentrated by gravity separation methods followed by froth flotation. Hydrophobicity is induced to sillimanite surface by adsorbing surfactant (oleic acid/oleate) molecules selectively and the mineral is collected into froth as concentrate. Other reagents used are; sodium silicate to depress garnet and silica and sodium hydroxide to adjust the pulp pH. In the present study, hydrotropes (sodium …

Applications of Nanocatalysis in Petroleum Industry
Abstract: This review paper briefly discusses about the important applications of nanocatalysts in petroleum industries. The design of materials in nanometer form is one of the most researched topics in the contemporary world. Catalysts have been widely used in chemical reactions to accelerate the reaction rate and to allow facile removal of product molecules. With the advent and growth of nanotechnology, catalysts were synthesized in nanometer scale. Nanocatalysts exhibited unique properties …

Review of Post-consumer Plastics and Pyrolysis Technology
Abstract: In both industrial and residential products, synthetic polymers are widely used. Since synthetic polymers are made from fossil fuels, they cannot decompose. disposal of plastic solid waste (PSW) has threatened the ecosystem seriously. In this article, we examine the various post-consumer PSW thermo-chemical recycling techniques. A method that has shown promise for converting PSW into valuable hydrocarbon compounds is pyrolysis. PSW has been broken down through thermal decomposition, however, value-added …

Solubility Enhancement of Paracetamol by Mixed Solvency Method
Abstract: The aim of this research work was to increase the solubility of poorly water soluble drugs by the mixed solvency method. This method is used for the proper pharmacological response. There are some techniques used for enhancing the solubility of poorly water soluble drugs. The recent trend possess that hydrotropic solution having high demand in industry because of some of its ideal features like easily available, having good recovery, does …

Soap Flotation: A Brief Review
Abstract: Homologues of fatty acids derived from vegetable oils/fats are used as collectors as such or as their soaps in the flotation of silicate/oxide/salt type minerals. Straight chain saturated fatty acid anions are envisaged to form compact adsorbed patches on the mineral surface which are more effective in imparting surface hydrophobicity to the minerals than the loose/fluffy patches formed by unsaturated fatty acid anions that are bent at the double bonds. …
