  水性条件下的醌甲基化物磷酸二酯烷基化。

  摘要：

  在水性条件下，已完成了对磷酸二酯与对醌甲基化物烷基化的详细分析。磷酸二酯烷基化和水解的相对速率已通过（1）NMR分析在缓冲的磷酸二乙酯/乙腈溶液（1：9 v / v，pH 4.0中）中的2,6-二甲基-对醌甲基化物的反应）。通过UV分析在pH 4.0和7.0下的28.5％的无机磷酸盐水溶液在乙腈中的溶液中UV分析确认了醌甲基化物的水解速率。同样，在28.5％的二苄基，二丁基或二乙基磷酸酯水溶液在pH 4.0和7.0的乙腈溶液中进行UV分析，也证实了醌甲基化物使磷酸二酯烷基化的速率。这些动力学研究进一步证实，磷酸二酯烷基化反应是酸催化的二级过程。

  Characterization of Dialkyldithiophosphates as Slow Hydrogen Sulfide Releasing Chemicals and Their Effect on the Growth of Maize

  摘要：

  Hydrogen sulfide is a key gasotransmitter for plants and has been shown to greatly increase their growth and survival in the presence of environmental stressors. Current methods for slowly releasing hydrogen sulfide use chemicals, such as GYY-4137, but these result in the release of chemicals not found in the environment, and chemicals used may lack structures that can be readily tuned to affect the rate of release of hydrogen sulfide. In this article, we describe the synthesis and slow release of hydrogen sulfide from dialkyldithiophosphates, which are a new set of hydrogen sulfide releasing chemicals that can be used in agriculture. The rates of hydrolysis of dibutyldithiophosphate and GYY-4137 were measured in water at 85 degrees C and compared with each other to investigate their differences. GYY-4137 is widely used as a chemical that slowly releases H2S, but its rate of release was not previously quantified. The release of hydrogen sulfide in water at room temperature was measured for a series of dialkyldithiophosphates using a hydrogen sulfide electrode. It was shown that the structure of the dialkyldithiophosphate affected the amount of hydrogen sulfide released. The final degradation products of dibutyldithiophosphate were shown to be phosphoric acid and butanol, which are chemicals found in the environment. This result was notable because it demonstrated that dialkyldithiophosphates degrade to safe, natural chemicals that will not pollute the environment. To demonstrate that dialkyldithiophosphates have potential applications in agriculture, maize was grown for 4.5 weeks after exposure to 1-200 mg of dibutyldithiophosphate, and the weight of corn plants increased by up to 39% at low loadings of dibutyldithiophosphate.
