    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of L-menthol capable of reducing expense for equipment to the possible lowest and increasing throughput by performing continuously as much as possible in an industrial scale, and to provide its molded article.SOLUTION: A manufacturing method of solid, especially flaky L-menthol is conducted by bringing molten L-menthol with 2 into contact with separated cooled surfaces. In the manufacturing method of menthol, the solidifying L-menthol molten product and the cooled surface has a surface parallel arrangement having 0.2 to 3 mm of distance from each other, each independently having a range of 0 to 35°C, and a contact time period between L-menthol and the cooled surface is 10 to 300 seconds. L-menthol exists as a solid, as at least up to 80 wt.% of transformation at contact with the cooled surface.

    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).
