Insert your thermometer into the small neck, using the red neoprene thermometer adapter to hold it securely. Prepare an ice bath. 4-NITROPHENOL is a slightly yellow, crystalline material, moderately toxic. Mixtures with diethyl phosphite may explode when heated. Decomposes exothermally, emits toxic fumes of oxides of nitrogen [Lewis, 3rd ed., 1993, p. 941].
