  Some mixed phosphites having two different alkyl chain were obtained as forerunners for mixed phosphates Mixed dialkyl phosphates were obtained in good yields (40-80%) by phase transfer catalysis in liquid-liquid sistem, starting from different dialkyl phosphites and aliphatic alcohols. The reaction conditions were optimized in order to obtain good yields in phosphites and phosphates respectively.

  A novel hydraulic fluid composition for application to drilling equipment is described herein. These hydraulic fluid compositions permit effective monitoring or controlling well-head pressure of a well during drilling on land or offshore. The hydraulic fluid compositions prevent uncontrolled flow of gas, oil, or another well fluid out of an underground formation during a drilling or extraction process when applied to the drilling equipment. Accordingly, provided is a hydraulic fluid concentrate which contains a water-soluble phosphate ester and a sulfide compound containing at least one S—S linkage, at least 10 carbon atoms and at least one terminal carboxylate group, wherein the S—S linkage bridges two alkyl groups. Additional components can be added to the concentrate and include one or more alkaline compound, one or more dicarboxylic acid or salt thereof, a water-soluble corrosion inhibitor, a water-soluble biocide, a pour point depressant, and water, ethylene glycol, or a combination thereof. The concentrate is then further diluted by the customer for use as described herein. Particularly, these compositions are effective in reducing seawater corrosion of a metal in contact with the hydraulic fluid composition, reducing bioaccumulation in oil drilling equipment contacted with the hydraulic fluid composition, and have low toxicity to sea life.

  本文介绍了一种应用于钻井设备的新型液压油组合物。这些液压流体组合物可以在陆地或近海钻井过程中有效监测或控制井口压力。在钻井或开采过程中，这些液压流体组合物应用于钻井设备时，可防止天然气、石油或其他井液不受控制地流出地下地层。因此，我们提供了一种液压油浓缩物，它含有水溶性磷酸酯和硫化物化合物，硫化物化合物含有至少一个 S-S 连接、至少 10 个碳原子和至少一个末端羧酸基，其中 S-S 连接桥接两个烷基。浓缩物中还可添加其他成分，包括一种或多种碱性化合物、一种或多种二羧酸或其盐、水溶性缓蚀剂、水溶性杀菌剂、降凝剂以及水、乙二醇或其组合。然后，客户将浓缩物进一步稀释，用于本文所述用途。特别是，这些组合物能有效减少与液压油组合物接触的金属在海水中的腐蚀，减少与液压油组合物接触的石油钻探设备中的生物累积，并且对海洋生物毒性低。
