标题:光学活性单酰基甘油:合成和纯度评估
摘要:尽管结构简单,但 1(或 3)-酰基-Sn-甘油的合成仍然是一个不容忽视的挑战,因为酰基迁移容易,这不仅使合成复杂化,而且使直接 Gc 或 HPLC 分析不可行.迄今为止,单酰基甘油光学纯度的评估几乎完全依赖于比旋光度数据,这些数据价值小,因此对杂质不敏感.现在,已经找到了一种"放大"小比旋光度的简单方法,以及测量 1,2-和 1,3-酰基迁移的实用方法,这些方法为 Mori 的 NMR 分析提供了一种方便且直接的替代方法.莫舍酯.借助这些方法,在合成两种天然单酰基甘油的过程中,研究了一系列脱丙酮的条件.

权利人:MIKROCAPS D O O
摘要:The present invention relates to biodegradable microcapsules with a membrane formed of a biodegradable composite material and their synthesis. Biodegradable microcapsules obtained as described in the present invention consist of a core material comprising at least one liquid water-immiscible active component, and a membrane that encloses this core material, the membrane consisting of a composite material comprising a carrier polymer framework and at least one filler deposited into the pores of said carrier polymer framework and deposited onto the surface of said carrier polymer framework, wherein the carrier polymer framework is made of at least one polymer and the filler is a lipophilic biodegradable organic compound which is solid at room temperature and has a melting point above 40° C. The thickness of the membrane is between 20 and 200 nm and the microcapsule diameter is between 1 and 50 pm. Biodegradable microcapsules as described in the present invention are used in the form of aqueous dispersions as additives to fabric softeners, detergents, pesticides, pharmaceutical ingredients, paints, cosmetics products and the like.

权利人:MIKROCAPS D O O
摘要:The present invention relates to a water dispersion of biodegradable microcapsules, with a membrane formed of a biodegradable crystalline material only, i.e. free of polymer framework, and synthesis thereof. Biodegradable microcapsules consist of a core material comprising at least one water-immiscible and water-insoluble active component, and a membrane that encloses this core material, the membrane consisting of a highly crystalline material only, wherein the crystalline material is a lipophilic biodegradable organic compound which is solid at room temperature and has a melting point equal to or above 40° C. Biodegradable microcapsules are in the form of aqueous dispersions and are used primarily for encapsulation of pesticides for use in pest control applications.
