Sodium hydroxide, flake

The methylamine generator consists of a i-l. flask fitted with a dropping funnel and outlet tube, which in turn is connected to a 25-cm. drying tower containing soda-lime, followed by a i-l. safety trap (Note 1). In the flask is placed 200 g. of technical sodium hydroxide flakes, and 263 g. of a 33-35 per cent solution of methylamine in water (Note 2) is dropped in slowly at such a rate that an even current of gas is evolved. When the addition has been completed and the gas bubbles very slowly into the...

The goods are entered into a bath containing 2-3 volume H O, 1 g/1 sodium hydroxide flake, 0.2 g/1 peroxide stabiliser, 0.25 g/1 sequestering agent and 0.002 to 0.05 g/1 free radical suppressor at 40 C, the temperature is raised to 85 C and then the treatment continued for 1 h. The treated goods are then cooled and rinsed thoroughly. When appropriate, selected optical brighteners may be incorporated in the peroxide bleach bath.

Step 3. A reactor is charged with water and 2-chloro-N,JV-dimethylethylamine hydrochloride. To the resulting solution is added an equivalent amount of 30 percent aqueous sodium hydroxide Toluene is added to the reactor, and the mixture is stirred to transfer the free base to the nonaqueous layer. The lower aqueous layer is drawn off, and the toluene solution of the free base is dried by the addition of anhydrous sodium carbonate and sodium hydroxide flakes ...
