Citrate as well as preparation method and application thereof

The invention relates to citrate as well as a preparation method and application thereof. The citrate solves the problem that toys prepared from existing citrate are viscous on the surface after beingpainted. Citric acid, isobutanol and capryl alcohol are taken as the raw materials, and citrate with the average molecular weight being 379.12-416.53 is generated under the effect of a catalyst; citrate with the purity being 99.5% or above is obtained after citrate in the last step is subjected to neutralization, washing, rectification, decoloration and filtration. The invention provides application of citrate to preparation of toys at the same time. The citrate can be widely applied to the field of toy production. 本发明涉及种柠檬酸酯及其制备方法和应用。本发明解决了现有柠檬酸酯生产的玩具喷漆后表面发黏问题，以柠檬酸、异丁醇和辛醇为原料，在催化剂的作用下生成平均分子量为379.12～416.53的柠檬酸酯；上述的柠檬酸酯经中和、水洗、精馏、脱色、过滤后得到纯度达99.5％以上的柠檬酸酯。本发明同时提供了其在玩具制备中的应用。本发明可广泛用于玩具生产领域。
