Abstract: The invention relates to a process for preparing low-by-product, light-color methylglycine-N,N-diacetic acid tri(alkali metal) salt by alkaline hydrolysis of methylglycinediacetonitrile (MGDN), comprising the steps in the sequence (a) to (f): (a) mixing of MGDN with aqueous alkali at a temperature of ≦̸30° C.; (b) allowing the aqueous alkaline MGDN suspension to react at a temperature in the range from 10 to 30° C. over a period of from 0.1 to 10 h to form a solution; (c) allowing the solution from step (b) to react at a temperature in the range from 30 to 40° C. over a period of from 0.1 to 10 h; (d) optionally allowing the solution from step (c) to react at a temperature in the range from 50 to 80° C. over a period of from 0.5 to 2 h; (e) optionally allowing the solution from step (c) or (d) to react at a temperature in the range from 110 to 200° C. over a period of from 5 to 60 min; (f) hydrolysis and removal of ammonia of the solution obtained in step (c), (d) or (e) by stripping at a temperature of from 90 to 105° C.

Abstract: A method is provided for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent with a boiling point ranging from -50° C. (223 K) to 200° C. (473 K) under atmospheric pressure, wherein the concentration of 3-chloropropyne in the liquid phase and in the gas phase is kept below the concentrations capable of deflagration by means of the type and amount of the diluent, the temperature and the total system pressure, together with the use of a 3-chloropropyne prepared, stored or transported in this way in the synthesis of dyestuffs, pharmaceutical and agricultural active ingredients, electroplating auxiliaries, disinfectants, steroids and growth hormones.

Abstract: The invention relates to a method for producing o-choromethyl benzenecarbonyl chlorides of formula (I), wherein R -R can be the same or different and stand for hydrogen, C1-C4-alkyl, halogen or trifluoromnethyl, by converting benzocondensed lactones of formula (II), wherein R -R have the aforementioned meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterized in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst
