In the laboratory, this liquid serves as a source of HCN, which is inconveniently volatile. [4] Thus, acetone cyanohydrin can be used for the preparation of other cyanohydrins, for the transformation of HCN to Michael acceptors, and for the formylation of arenes. Treatment of this cyanohydrin with lithium hydride affords anhydrous lithium cyanide:
The Dosage Index is a mathematical figure used by breeders of Thoroughbred race horses, and sometimes by bettors handicapping horse races, to quantify a horse's ability, or inability, to negotiate the various distances at which horse races are run. It is calculated based on an analysis of the horse's pedigree.
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
It is used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium cyanide: [8] (CH 3) 2 C(OH)CN + LiH → (CH 3) 2 CO + LiCN + H 2. In transhydrocyanation, an equivalent of HCN is transferred from acetone cyanohydrin to another acceptor, with acetone as byproduct. The transfer is an equilibrium process, initiated by ...
A woman got a lot more than she bargained for when she stopped to give a treat to a friendly Highland cow at the Natural Bridge State Park in Virginia.
Edward Wayne Edwards confessed to murdering five people, including a teenage couple. Edwards' daughter, April Balascio, believes there are more victims.
For any given horse, the dosage profile is generated by assigning points for each Chef-de-race in the pedigree, with the number of points varying depending on what generation the chef appears in. The Dosage Index can then be calculated, with a higher number meaning the pedigree is more speed-oriented.
