  Allylic styrene ether compounds of the formula: where R1 is an optionally substituted allylic or propargyl hydrocarbon group, and R2, R3, and R4 are independently H, C1-6 hydrocarbon or C1-6 hydrocarbonoxy groups, are prepared in a single pot reaction from relatively low cost materials. The method includes the steps of reacting a 4-acyloxystyrene of the formula where R is an acyl group, with at least one mole of a base which can readily saponify or hydrolyze the phenolic ester bond per mole of acyloxystyrene, and then adding to the reaction mixture an alkylating agent of the formula R1X, where R1 is as previously defined and X is chloride, bromide, iodide, a sulfonic ester or a hydrocarbon sulfate group, to form said allylic styrene ether compound. The method may be employed to prepare mono-styryl functional compounds or distyryl functional compounds such as 1,4-bis(4'-vinylphenoxy)but-2-ene.

  公式为：其中R1是可选择性取代的烯丙基或丙炔基碳氢基团，而R2、R3和R4分别是H、C1-6碳氢基团或C1-6碳氢氧基团的烯丙基苯乙醚化合物可以从相对低成本的材料中通过单锅反应制备。该方法包括以下步骤：将公式为的4-酰氧基苯乙烯（其中R为酰基）与至少一摩尔的碱反应，该碱可以轻易皂化或水解酚酸酯键，每摩尔酰氧基苯乙烯，然后向反应混合物中加入公式为R1X的烷基化剂，其中R1如前所述，而X是氯化物、溴化物、碘化物、磺酸酯或碳氢基硫酸酯基，以形成所述的烯丙基苯乙醚化合物。该方法可用于制备单苯乙烯基功能化合物或双苯乙烯基功能化合物，例如1,4-双(4'-乙烯基苯氧基)丁-2-烯。

  Subjects for the present invention are to provide a thickening agent for excavation stabilizing slurries which has excellent cement contamination resistance, is difficult to putrefy, and is prevented from bubbling, which may be problematic in construction works, and to provide an excavation stabilizing slurry containing the thickening agent and a cast-in-place underground pile method and an diaphragm wall construction method each using the slurry. The present invention provides a thickening agent for excavation stabilizing slurries which contains an emulsion thickening with an alkali, wherein in a strong agitation bubbling test of a mixture prepared by adding an alkaline substance to the thickening agent, the resulting mixture has an apparent specific gravity of 1.05 g/ml or higher as measured immediately after the strong agitation and has an apparent specific gravity of 1.10 g/ml or higher as measured at 10 minutes after the strong agitation. This thickening agent is used to prepare an excavation stabilizing slurry.

  本发明的目的是提供一种用于开挖稳定泥浆的增稠剂，该增稠剂具有优异的抗水泥污染性，不易腐烂，并可防止在建筑工程中可能出现问题的起泡现象，以及提供一种含有该增稠剂的开挖稳定泥浆和一种使用该泥浆的现浇地下桩工法和一种地下连续墙施工方法。 本发明提供了一种用于开挖稳定泥浆的增稠剂，该增稠剂含有一种用碱增稠的乳液，在对向增稠剂中加入碱性物质制备的混合物进行强力搅拌起泡试验时，在强力搅拌后立即测量所得混合物的表观比重为 1.05 克/毫升或更高，在强力搅拌后 10 分钟测量所得混合物的表观比重为 1.10 克/毫升或更高。这种增稠剂用于制备挖掘稳定泥浆。
