As Mrs. Knowles complained to Dr. Johnson, ‘the mason’s wife, if she is ever seen in liquor, is ruined; the mason may get himself drunk as often as he pleases with little loss of character.’1 The ruin resulted not just from the liquor itself but...
The invention relates to a reactive emulsifier and a preparation method and application of the emulsifier, especially to an emulsifier with a bifunctional group and a hydrophilic structure, wherein the emulsifier can improve dispersion and anticoagulation performance of an emulsion, and a reactive struct...

those in which only the hydrogen in the hydroxyl group is replaced, e.g., the reaction of ethanol with sodium, an active metal, to form sodium ethoxide and hydrogen; and those in which the carbon-oxygen bond becomes a double bond to form an aldehyde or ketone depending on whether it is...
ChEBI: A long chain fatty alcohol that is octadecanol containing a double bond located at position 9 (the Z-geoisomer). Production Methods Oleyl alcohol occurs naturally in fish oils. Synthetically, it can be prepared from butyl oleate by a Bouveault–Blanc reduction with sodium and butyl alcoho...
