Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing crystals of small grain sizes and simultaneously a narrow grain size distribution. SOLUTION: The method for crystallizing the crystals below 100 μm in average grain size comprises performing crystallization by simultaneously using ultrasonic waves to be directly introduced by using a sonotrode into a solution or suspension of a compound to be crystallized and a specific proportional agitation driving power.

Abstract: The invention relates to a method for producing trioxane by the trimerization of formaldehyde in an aqueous acidic solution and by subsequently separating out trioxane from a mixture (trioxane raw product) essentially consisting of trioxane, water and formaldehyde. The invention is characterized in that: a) the trioxane raw product from the trimerization is distilled; b) the trioxane is crystallized out; c) is separated out from the mother liquor; d) is subsequently melted, and; e) additional byproducts are removed by distillation.

Abstract: The invention relates to a process for isolating methylglycinenitrile-N,N-diacetonitrile (MGDN) from an aqueous emulsion which comprises MGDN and has an MGDN content of 3-50% by weight in a crystallizer, comprising the steps: (a) the aqueous emulsion is, starting from a temperature above the solidification point, cooled to a temperature below the solidification point, the cooling rate averaged over time not exceeding 5 K/h, until substantially the entirety of the emulsified MGDN has solidified, (b) the resulting aqueous suspension is cooled further and/or concentrated, and the cooling rate may be greater than in step (a).
