Abstract: 1319497 Anilides BADISCHE ANILIN- & SODA-FABRIK AG 29 Oct 1970 [30 Oct 1969] 51410/70 Heading C2C Compounds of the general formula (R = C 2-6 alkyl or alkenyl; X = Cl, Me, OMe and/or CF 3 ; n = 1 or 2; m = 1-4 or 8) are prepared by acylating the corresponding anil. These compounds are selective herbicides, and may be used in the form of compositions containing them together with a carrier.

Abstract: Process for producing dry, free-flowing, choline chloride-containing powders by atomising an aqueous choline chloride solution, a colloid-free aqueous choline chloride solution being atomised in a counter-current airstream which contains, finely dispersed, a hydrophobic spraying aid added in amounts such that the sprayed choline chloride droplets are coated with 2 to 15% by weight, based on choline chloride calculated as 100%, and the coated particles, if required, are collected in a fluid bed and dried in the gas stream.

Abstract: A process for the preparation of free-flowing, dust- and binder-free riboflavine spray granulates or microgranulates from finely divided pure riboflavine, characterised in that an aqueous or water-containing suspension of the pure finely divided riboflavine is subjected to a) fluidised bed spray drying, b) single component nozzle atomiser drying or c) disc atomiser drying, in particular fluidised bed spray drying, without binder being added to the suspension, and the riboflavine spray granulates or microgranulates obtainable according to this process.

Abstract: An improved process for preparing riboflavin 5'-phosphate monosodium salt by reacting riboflavin or its sodium salt with excess phosphorus oxychloride in a suitable organic solvent, hydrolysing the resulting reaction mixture by treating with water at elevated temperature, reacting the reaction mixture obtained in the hydrolysis with a sodium-containing base to a pH of 4.0 to 6.0, and isolating the riboflavin 5'-phosphate sodium salt crystallising out which is characterised in that the reaction mixture obtained in the hydrolysis is reacted with sodium-containing base at such high temperatures that the riboflavin 5'-phosphate to be reacted is completely dissolved in the reaction mixture. Suitable temperatures are 50 to 100 DEG C.

Abstract: Prodn. of gamma-lactones of formula (I) is effected by (a) heating a culture broth contg. the corresp. hydroxy acid to 60-130 deg. C without adding acid, and (b) extracting (I) in conventional mannner. In (I) R = 4C or 6C alkyl. The broth is heated at 80-120 deg. C for 30-150 (esp. 60-90) min. USE/ADVANTAGE - (I) are useful as flavours and fragrances. The process uses fewer chemicals than prior art processes employing mineral acids for lactonisation (cf.US4560656 and WO8912104), so the prods. should be more acceptable to consumers.
