| titleOfInvention | Method for adjusting particle size during crystallization of dimethylolalkanoic acid |
| abstract | The present invention relates to compounds of the general formula (I) of the general formula (I) in which R is the same or different and represents a methylol group or a substituted or unsubstituted aliphatic hydrocarbon group, having a substantially monomodal particle size distribution. It relates to a method for selectively crystallizing poly- or monomethylolalkanoic acids. This is achieved by crystallization in the temperature range from 85 ° C. to 50 ° C. while maintaining a cooling rate of less than 10 K / h, whereby essentially trigonal symmetric crystals are obtained. The invention relates to a process in which the crystallization is carried out at a temperature below 50 ° C. or at a temperature in the range from 50 ° C. to 5 ° C. while maintaining a cooling rate of less than 15 K / h, essentially a single-mode particle size. Selectively crystallizing a poly- or monomethylolalkanoic acid of general formula (I) having a distribution, wherein R is the same or different and represents a methylol group or a substituted or unsubstituted aliphatic hydrocarbon group. It also relates to the method of conversion. |
