The 1,1,2,2-tetrachloroethane is then dehydrochlorinated to give trichloroethylene. This can be accomplished either with an aqueous solution of calcium hydroxide: 2 Cl 2 CHCHCl 2 + Ca(OH) 2 → 2 ClCH=CCl 2 + CaCl 2 + 2 H 2 O. or in the vapor phase by heating it to 300–500 °C on a barium chloride or calcium chloride catalyst: Cl 2 CHCHCl 2 ...
[1] [8] The standard quality of Java type from Indonesia is regulated by Indonesian authority under SNI 06–3953–1995, which requires citronellal minimum 35% and total geraniol minimum 85%. [ 9 ] Both types probably originated from Mana Grass of Sri Lanka, which according to Finnemore (1962) occurs today in two wild forms – Cymbopogon ...

Polyethylene glycol (PEG; / ˌ p ɒ l i ˈ ɛ θ əl ˌ iː n ˈ ɡ l aɪ ˌ k ɒ l,-ˈ ɛ θ ɪ l-,-ˌ k ɔː l /) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine.
A constant blood concentration of 1 to 1.5 g/L (corresponding to 0.5 to 0.75 mg/L in the breath) should be maintained to acceptably saturate the enzyme. An initial dose of 0.6 to 0.7 g ethanol per kilogram body weight should be given (about 0.8 mL/kg or 0.013 fl.oz/lb). This will cause ethanol intoxication. To avoid adverse effects, frequent ...
However, according to the U.S. Department of Agriculture's FoodData Central database, as of a few years ago, more than 8,000 branded food products still contained Red Dye No. 3.
Polyethylene glycol propylene glycol cocoates or PEG propylene glycol cocoates are chemical compounds produced by the esterification of polyoxyalkyl alcohols with fatty acids from coconut oil (primarily lauric acid). [1] Their chemical designation is PEG-8, [2] referring to its polyethylene glycol (PEG) molecular chain length.
