Abstract: Regenerating plastic diaphragms comprises mixing a soln. of mineral acid (I) with a corrosion inhibitor (II) and passing the mixt. through the diaphragm for 0.1-84 (pref. 1-72, esp. pref. 2-24) hrs. at 0-100 (pref. 40-80, esp. pref. 50-70) degrees C. Also claimed are plastic diaphragms obtd. by this process. (I) consists at least partly, pref. entirely, of HCl in a concn. of 0.3-20 (pref. 2-10) wt%, pref. contg. NaCl in a concn. up to the satn. pt., pref. up to 250 g/l. Pref. soln. (I) also contains 500-5000 ppm Cu and/or Fe cpds., esp. Cu(II) and/or Fe(III) salts. The mixt. contains 0.005-5 (pref. 0.05-0.5) wt% (II). Component (II) contains alkynol(s), esp. an alkyne-diol, pref. mixed with 1-25 wt% amine, esp. hexamethylenetetramine (HMTA), ethylhexylamine or diethylhexylamine, and/or 0.1-3 wt% surfactant, esp. a quat. ammonium salt.

Abstract: The invention relates to a method for producing highly pure LiBF4 by prepari ng a solution of BF3 etherate in diethyl ether, suspending LiF in this solution, converting same into solid LiBF4 and then separating t he resulting solid LiBF4. The invention also relates to the use of LiBF4 obtained in this manner for the production of lithium-ion batteries .

Abstract: Alkali metal methoxides are prepared from aqueous alkali metal hydroxide, which may have been admixed with methanol, and methanol in a reaction column having at least 5, preferably from 15 to 30, theoretical plates between the feed point for the aqueous alkali metal hydroxide and the feed point for the methanol. The gaseous methanol/water mixture formed in the reaction is fractionated in a rectification column. In one variant of the invention, the trays chosen for the reaction column configured as a bubble cap tray, valve tray or sieve tray column are trays in which not more than 5%, preferably
