Valley. A valley is usually found between two ranges of hills rather than between two hills. The small "valley" between two hills is more properly called a "coll".

Answer the integumentary system (skin), sweets when you are hot so it releases "water" to coll you down.And you shiver with your muscular system(i think) you produces heat to warm you up!.


How can I preparae methylethylketoxime from the reaction between MEK and hydroxylamine hydrochloridde?

Normally you just take equimolar amounts of both, add a weak base and stir for a certain time (probably with slightly higher temperature). Because it's a liquid you could extract it after the reaction with MTBE or so, evaporate the solvent and distill under reduced pressure or just take a column for purification.Excerpt:"Formaldoxime. A mixture of 11.5 g. (0.38 mole) of paraformaldehyde and 26.3 g. (0.38 mole) ofhydroxylamine hydrochloride in 170 ml. of water is heated until a clear solution is obtained. Then thereis added 51 g. (0.38 mole) of hydrated sodium acetate, and the mixture is boiled gently under reflux for15 minutes to give a 10% solution of formaldoxime."Organic Syntheses, Coll. Vol. 5, p.139 (1973); Vol. 46, p.13 (1966).OR:"In a 5-l. two-necked flask, fitted with a mechanical stirrer, a reflux condenser, a thermometer, and aseparatory funnel, are placed an aqueous solution of 348 g. (5 moles) of hydroxylamine hydrochloride(Org. Syn. Coll. Vol. I, 1941, 318) in 600 cc. of cold water and 460 g. (4 moles) of heptaldehyde (Note1). Stirring (Note 2) is started, and a solution of 265 g. (2.5 moles) of anhydrous c.p. sodium carbonatein 500 cc. of water is added at such a rate that the temperature of the reaction mixture does not riseabove 45°. Stirring is continued at room temperature for an hour after the addition of the sodiumcarbonate solution is complete."Organic Syntheses, Coll. Vol. 2, p.313 (1943); Vol. 11, p.54 (1931).- It should be quite the same with MEK - so just have a try!
