查询词典 adamantine boron

Little literature on the aspect of surfactants containing boron with long-carbon chain alkyls had been found.Using diethanolamine, boric acid, hexadecanol as starting materials, after a series of reaction such as vapour phase process bromizating, esterifying, alkylating, a new type of surfactants with boron RNB had been obtained. The structures of the compounds had been identified by elemental analysis, IR and HNMR.

本论文采用二乙醇胺、硼酸、十六醇等为主要原料，经气相法溴化、酯化、烷基化等一系列反应合成了一种新型含硼表面活性剂RNB，并通过元素分析、红外、核磁对其结构进行了确认。

During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.

在低压低渗透气藏的压裂改造过程中，常规羟丙基胍胶-有机硼交联压裂液体系存在的主要问题，一是压裂液滤液对低压低渗透气层造成的水锁损害；二是常规羟丙基胍胶-有机硼压裂液是在碱性条件下交联的，对碱敏性储层造成碱敏损害，降低储层渗流能力；三是地层压力低，压裂液返排能量不足，当前各油田采取的措施主要是&液氮伴注&技术，但是&液氮伴注&技术增加了压裂的费用，而且液氮存放也存在较大问题。

Mentions of boron compounds like borax date back millennia. In 1808, within a week and a half of each other, two research efforts, led by the great chemists Sir Humphrey Davy in London and Joseph Louis Gay-Lussac and Louis-Jacques Thénard in Paris, announced that they had isolated boron.

硼的一种化合物硼砂被提及的年代可以追溯到一百万年前。1808年，在间隔一个半星期的时间内，分别由伦敦的Sir Humphrey Davy以及巴黎的Joseph Louis Gay-Lussac和Louis-Jacques Thénard领导的两项研究成果均声称他们分离出了硼单质。

Tested the volatilization of boron through the acid-alkali neutralization titration, analyzed the influencing factor of boron volatilization, the conclusion showed that the moisture content and heating-up time were important factor; observed the phase splitting by the SEM, the conclusion showed that the phase splitting were all connected state.
