Abstract: In the continuous process for preparing alkylamines by reacting C1-4-alkanols with ammonia in the gas phase in the presence of a shape-selective fixed-bed catalyst in a cooled reactor, the shape-selective fixed-bed catalyst is present in a single contiguous fixed bed in the reactor and tubes through which coolants are passed run within the fixed bed to regulate the temperature of the fixed bed.

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: A process for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent having a b.pt. of ?-50-200 deg C (normal pressure) is characterized by maintaining the concentration of 3-chloropropyne in the liquid phase and gas phase below the deflagration concentration by control of the type and amount of diluent, and by temperature and total pressure of the system.

Abstract: The invention relates to a method for producing acid chlorides by converting carboxylic acids with carbon oxychlorides or thionyl chloride in the presence of a catalyst adduct of an N,N-disubstituted formamide of general formula (I) and carbon oxychloride or thionyl chloride. In the formula, R and R , independently from one another, mean C1- to C4-alkyl or R and R together mean a C4- or C5-alkylene chain. According to the inventive method, hydrogen chloride is added during and/or after the conversion.

Abstract: Recovery of neopentyl hydroxypivalate (I) from a mixture containing (I), products (II) of lower boiling point, products (III) of higher boiling point and inorganic salts (IV) is carried out in 2 separation stages. In stage (1), the mixture is fed to a wiped film evaporator; (III) and (IV) are discharged from the sump; and a vapor stream of (I), (II) and (III) is discharged via the top to a heat transfer unit, where it is condensed. In stage (2), the condensate is fed into a rectifying column with a second evaporator and heat transfer; a vapor stream of (II) is discharged at the top, condensed and optionally partly recycled as reflux and partly discharged; a vapor stream of (I) is discharged at the side and condensed; and a stream of (I) and (III) is discharged from the sump and (partly) passed to the second evaporator, the vapor from this evaporator being (partly) recycled to the lower zone of the column. Also claimed is the apparatus used.

Abstract: Neopentyl glycol hydroxypivalate is isolated from a reaction mixture obtained from a Tishchenko reaction of hydroxypivalaldehyde in the presence of calcium hydroxide, barium hydroxide or strontium hydroxide, by adding acid, removing the salts formed by adjusting the water content in the reaction mixture to 20-60% and extracting the salts at above 50 DEG C. and working up the residual mixture by distillation.
