Production and Reactions
Spirit of amber was originally obtained from amber by pulverising and distilling it using a sand bath. In the past it was chiefly used externally for rheumatic aches and pains, and internally in inveterate gleets.
Succinic acid is produced by several methods. Common industrial routes include hydrogenation of maleic acid, oxidation of 1,4-butanediol, and carbonylation of ethylene glycol.
Succinic acid can be converted into fumaric acid by oxidation. The diethyl ester is a substrate in the Stobbe condensation. Dehydration of succinic acid gives succinic anhydride.

Famous quotes containing the words production and, production and/or reactions:
“Production and consumption are the nipples of modern society. Thus suckled, humanity grows in strength and beauty; rising standard of living, all modern conveniences, distractions of all kinds, culture for all, the comfort of your dreams.”
—Raoul Vaneigem (b. 1934)
“An art whose limits depend on a moving image, mass audience, and industrial production is bound to differ from an art whose limits depend on language, a limited audience, and individual creation. In short, the filmed novel, in spite of certain resemblances, will inevitably become a different artistic entity from the novel on which it is based.”
—George Bluestone, U.S. educator, critic. “The Limits of the Novel and the Limits of the Film,” Novels Into Film, Johns Hopkins Press (1957)
“Separation anxiety is normal part of development, but individual reactions are partly explained by experience, that is, by how frequently children have been left in the care of others.... A mother who is never apart from her young child may be saying to him or her subliminally: “You are only safe when I’m with you.””
—Cathy Rindner Tempelsman (20th century)
