  一种4-乙烯基吡啶丙磺酸内鎓盐的合成方法

  摘要：

  本发明提供一种4‑乙烯基吡啶丙磺酸内鎓盐的合成方法，步骤如下：分别称取4‑乙烯基吡啶、1,3‑丙磺酸内酯、有机溶剂和助剂；将有机溶剂平均分成三份，分别与4‑乙烯基吡啶、1,3‑丙磺酸内酯、助剂溶解混合；然后将混合溶液依次加入反应器，在20℃～90℃的条件下反应1～10h，然后经过滤、洗涤、干燥制得4‑乙烯基吡啶丙磺酸内鎓盐。本发明方法通过加入助剂，不仅产品收率高，可达90%以上，而且不需要经过重结晶步骤直接得到高纯度产品，产品纯度≥95%。本发明方法具有反应时间短、操作简单，反应后反应器不挂胶，易于清洗维护，有利于工业化生产，适于工业应用。

  Disclosed is a starch-containing microsphere and a preparation method thereof and an application thereof. The particle size of the starch-containing microsphere exhibits polydispersity with uniform distribution in a particle size concentrated distribution interval, and the particle size distribution in the particle size concentrated distribution interval has the following features: equal division of the particle size concentrated distribution interval into n intervals, and a microsphere percentage in each interval is (I), where n is an integer greater than 1. The preparation method comprises: first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres prepared by the present invention are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 µm. 100n%±10n%

  Disclosed are an associated copolymer, a method for preparation of a polymer and a polymer prepared with the method, a use of the associated copolymer and/or the polymer in drilling fluids, and a drilling fluid containing the associated copolymer and/or the polymer. The associated copolymer comprises acrylamide structural units, zwitter-ionic structural units, and cationic polyamine structural units at a specific proportion, and the cationic polyamine structural units have specific kinematic viscosity and cationic degree; thus, when the associated copolymer is used as a viscosity improver for drilling fluids, the obtained drilling fluid not only has favorable apparent viscosity after it is aged at a high temperature, but also has high dynamic shear force, and is resistant to high temperature up to 200° C. or above, resistant to NaCl up to saturated concentration, and resistant to CaCl 2 up to 20 wt % concentration.

  A starch-containing microsphere has a particle size that exhibits polydispersity with uniform distribution in a particle size concentrated distribution interval. The particle size distribution in the particle size concentrated distribution interval has the following features: equal division of the particle size concentrated distribution interval into n intervals, and a microsphere percentage in each interval is formula (I), 100 n   % ± 1  0 n   % , ( I ) where n is an integer greater than 1. The preparation method of the starch-containing microsphere includes: first reacting starch with a low concentration of epichlorohydrin, and then reacting the resultant product with a surfactant, followed by final crosslinking to give microspheres. The starch-containing microspheres thus prepared are polydisperse starch-containing microspheres with a uniform particle size distribution, with the particle size being in a range of 0.1-500 μm.
