The acid, when distilled slowly, is decomposed and yields a and 0-angelica lactones.
When heated with hydriodic acid and phosphorus, it yields n-valeric acid; and with iodine and caustic soda solution it gives iodoform, even in the cold.
It is reduced by sodium amalgam to glycouril C 4 H 6 N 4 O 2, whilst with hydriodic acid it yields urea and hydantoin C 3 H 4 N 2 O 2.
Pasteur found that, when cane sugar was fermented by yeast, 49.4% of carbonic acid and 51.1% of alcohol were produced; with expressed yeast juice cane sugar yields 47% of carbonic acid and 47.7% of alcohol.
Mannheim is the chief commercial town on the upper Rhine, and yields in importance to Cologne alone among the lower Rhenish towns.
When heated with hydriodic acid (specific gravity 1.96) it forms amino-acetic acid, and with tin and hydrochloric acid it yields ethylene diamine.
It is monobasic and yields salts which only crystallize with great difficulty; when liberated, from these salts by a mineral acid it forms a syrupy nonvolatile mass.
It yields a silver salt which with ethyl iodide forms benzimido-- ethyl ether, C 6 H 5 C: (NH) ï¿½OC 2 H 5, a behaviour which points to.
The sea produces three different seals, which often ascend rivers from the coast, and can live in lagoons of fresh water; many cetaceans, besides the " right whale " and sperm whale; and the dugong, found on the northern shores, which yields a valuable medicinal oil.
The " leathery turtle," which is herbivorous, and yields abundance of oil, has been caught at sea off the Illawarra coast so large as 9 ft.
The richest quality yields about 100 to 130 gallons of crude oil per ton, or 17,000 to 18,000 cub.
On oxidation with chromic or nitric acids, or potassium permanganate, it yields nicotinic acid or (3-pyridine carboxylic acid, C 5 H 4 N CO 2 H; alkaline potassium ferricyanide gives nicotyrine, C10H10N2, and hydrogen peroxide oxynicotine, C10H14N20.
Oxidation of its isomethylhydroxide with potassium permanganate yields trigonelline, C 7 H 7 NO 2 (A.
With bromine in acetic acid solution at ordinary temperature, nicotine yields a perbromide, C10H10Br2N20 HBr 3, which with sulphur dioxide, followed by potash, gives dibromcotinine, C10H10Br2N20, from which cotinine, C10H12N20, is obtained by distillation over zinc dust.
By passing the vapour of this compound through a red-hot tube, it yields the isomeric a0- pyridylpyrrol, the potassium salt of which with methyl iodide gives a substance methylated both in the pyridine and pyrrol nuclei.
When scratched, it yields a black streak.
Crop yields are highly volatile and unpredictably so.
Those who argue they should not say there is no way for poor countries to compete with mechanized Western farming and the extremely high yields it produces.
And, by the way, who estimates the value of the crop which nature yields in the still wilder fields unimproved by man?
