摘要

Crystal stabilized 2 - ethyl - 3.7 - dimethyl - 6 - (4 - (trifluormetoxi) quinoline - 4 - ilmetil carbonate, process for the production of the crystal, and agricultural chemical composition comprising the crystal. An objective of the invention is currently producing a crystal of 2 - ethyl - 3.7 - dimethyl - 6 - (4 - (trifluormetoxi) phenoxy) quinoline - 4 - ilmetil carbonate having physical and chemical properties are stable.The goal is achieved in a crystal of 2 - ethyl - 3.7 - dimethyl - 6 - (4 - (trifluormetoxi) phenoxy) quinoline - 4 - ilmetil carbonate has a peak of the diffraction pattern shown in Figure 1 difratometria as determined by X-ray powder.
