  • Neopentyl Glycol
  • Techno-economic analyses of specific Neopentyl Glycol production processes, presenting capital investment breakdown, raw materials consumed and operating costs. (slideshare.net)
  • 1. Know the capital investment required Examine the operating costs & raw materials consumption Neopentyl Glycol is an organic compound used in the synthesis of polyesters (enhances the stability of the product towards heat, light, and water), paints, lubricants, and plasticizers. (slideshare.net)
  • The Intratec portfolio (www.intratec.us/our-portfolio) includes reports examining specific Neopentyl Glycol production processes. (slideshare.net)
  • For a 10-page description of our methodology, visit www.intratec.us/reports/industrial-processes-economics Reports Focused on Neopentyl Glycol Production Economics ECONOMICS OF NEOPENTYL GLYCOL PRODUCTION PROCESS (NEOPENTYL GLYCOL E11A) This report presents the economics of Neopentyl Glycol production from isobutyraldehyde, formaldehyde and hydrogen, assuming a conventional industrial process. (slideshare.net)
  • Different from the report "Neopentyl Glycol E11A", the economic analysis presented in this study is based on a plant constructed in China. (slideshare.net)
  • Neopentyl glycol is synthesized industrially by the aldol reaction of formaldehyde and isobutyraldehyde. (wikipedia.org)
  • This creates the intermediate hydroxypivaldehyde, which can be converted to neopentyl glycol with either excess formaldehyde or catalytic hydrogenation of the aldehyde group to an alcohol group. (wikipedia.org)
  • vapor
  • Due to the composition of the rich glycol, a vapor phase having a high hydrocarbon content will form when the pressure is lowered. (wikipedia.org)
  • Reagents
  • Periodic acid (HIO4) and lead tetraacetate (Pb(OAc)4) are the most common reagents used for glycol cleavage, processes called the Malaprade reaction and Criegee oxidation, respectively. (wikipedia.org)
  • typically
  • Further purification produces finished industrial grade or USP/JP/EP/BP grade propylene glycol that is typically 99.5% or greater. (wikipedia.org)
  • Glycol dehydration units must typically meet this specification at a minimum, although further removal may be required if additional hydrate formation temperature depression is required, such as upstream of a cryogenic process or gas plant. (wikipedia.org)
  • chemical
  • PEGs and methoxypolyethylene glycols are manufactured by Dow Chemical under the tradename Carbowax for industrial use, and Carbowax Sentry for food and pharmaceutical use. (wikipedia.org)
  • A popular application is in beverage production, wherein propylene glycol - a food grade chemical - is used (see Glycol). (wikipedia.org)
  • Dinitrate
  • Like other organic nitrates, ethylene glycol dinitrate is a vasodilator. (wikipedia.org)
  • C3H6(ONO2)2 → 3 CO + 3 H2O + N2 The principal current use of propylene glycol dinitrate is as a propellant in Otto Fuel II, together with 2-nitrodiphenylamine and dibutyl sebacate. (wikipedia.org)
  • Nitrates of polyhydric alcohols, of which propylene glycol dinitrate is an example, have been used in medicine for the treatment of angina pectoris, and as explosives since the mid-nineteenth century. (wikipedia.org)
  • Dehydration
  • Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). (wikipedia.org)
  • The purpose of a glycol dehydration unit is to remove water from natural gas and natural gas liquids. (wikipedia.org)
  • Glycol dehydration units depress the hydrate formation point of the gas through water removal. (wikipedia.org)
  • poisonous
  • At first, scientists thought that DEG metabolized into ethylene glycol, which is poisonous due to the metabolic production of glycolic acid, glyoxylic acid, and ultimately oxalic acid. (wikipedia.org)
  • purity
  • Lean, water-free glycol (purity >99%) is fed to the top of an absorber (also known as a "glycol contactor") where it is contacted with the wet natural gas stream. (wikipedia.org)
  • The glycol is thermally regenerated to remove excess water and regain the high glycol purity. (wikipedia.org)
  • alcohol
  • Wurtz named his new compound "glycol" because it shared qualities with both ethyl alcohol (with one hydroxyl group) and glycerin (with three hydroxyl groups). (wikipedia.org)
  • Glycol chillers are a specific kind of refrigeration system, often used to cool a variety of liquids - including alcohol and other beverages. (wikipedia.org)
  • mixture
  • Pure EGDN was first produced by the Belgian chemist Louis Henry (1834-1913) in 1870 by dropping a small amount of ethylene glycol into a mixture of nitric and sulfuric acids cooled to 0 °C. The previous year, August Kekulé had produced EGDN by the nitration of ethylene, but this was actually contaminated with beta-nitroethyl nitrate. (wikipedia.org)
  • carbon
  • Ethylene glycol is produced from carbon monoxide in countries with large coal reserves and less stringent environmental regulations. (wikipedia.org)
  • The carbon-carbon bond in a vicinal diol (glycol) is cleaved and instead the two oxygen atoms become double-bonded to their respective carbon atoms. (wikipedia.org)
  • Propylene glycol contains an asymmetrical carbon atom, so it exists in two enantiomers. (wikipedia.org)
  • The glycol unit has just three carbon atoms and still shows Watson-Crick base pairing. (wikipedia.org)
