I don't understand the synthesis proposed in Rhodium. For that so much cold? Would not it harm the dehydration and therefore the formation of the
insaturate?

Organic Syntheses, Coll. Vol. 1, p.413 (1941); Vol. 9, p.66 (1929). has a few notes about this rxn.

Its to keep the nitromethane from being degraded by the sodium hydroxide. The strong cold is very important with this method of preparation. This is
not the case with the more known methods of nitrostyrene synthesis, e.g. with an amine catalyst.
Actually, the method you posted prepares the sodium nitroalcoholate in the cold first, and the elimination of water to form nitrostyrene only happens
when the mixture is poured into HCl as in the preparation.

How can one obtain the sodium salts of nitromethane (I mean to isolate them)?
