Microwave irradiation technique for synthesis of dialkyl dithiophosphoric acids

Microwave heating technique was applied to the preparation of dialkyl dithiophosphoric acids from the reaction of alcohol with phosphorus pentasulphide. A microwave oven (CEM-MDS 2000) was utilized to determine the preparation conditions for the best yield of dialkyl dithiophosphoric acids under atmospheric pressure at various times and power. Six different (C4-C9) chain-length of dialkyl dithiophosphoric acids were studied. All experiments were performed in an open Teflon (poly-tetrafluoroethylene) vessel. The results obtained showed that the reaction of dialkyl dithiophosphoric acids can be achieved more rapidly using microwave heating than using conventional procedures.

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

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 °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.

Dicarboxylic acid derivatives containing dialkyldithiophosphate group and antiwear additives and lubricant compositions comprising the same

The present invention relates to dicarboxlic acid derivatives containing a dialkyl dithiophosphate group, and a wear-resistant additive and a lubricant composition comprising the same. According to the present invention, a lubricant composition comprising a dicarboxlic acid derivative compound having a dialkyl dithiophosphate group has excellent wear resistance compared to an existing lubricant composition, shows excellent effects even with a lower content than existing lubricating oil compositions, and is environment-friendly because heavy metals are not used. Accordingly, the lubricant composition can be usefully used as an additive of engine oil, lubricating oil for transmission, gear-oil, turbine oil, working oil, refrigerant oil, compressor oil, vacuum pump oil, bearing oil, sliding surface oil, metal cutting oil, plastic working oil, heat treatment oil, lubricating oil or processing oil.COPYRIGHT KIPO 2017
