In this article the regulations and policy about S and Ncontaining compounds in fuels, the general information about methods of desulfurization (DS) and denitrogenation (DN) and ionic liquids (ILs) assisted DS and DN are considered. We presented the most effective and novel methods of sulfur and nitrogen compounds removal using ILs from model and real fuels.

: In this review article, we present the latest research in the field of ionic liquids containing biologically active anions and cations, their potential application in the field of agrochemistry and agriculture. The article describes examples of the use of ionic liquids as herbicides, fungicides, antimicrobial agents, deterrents and plant growth stimulants. It also indicates the advantages and disadvantages of using of ionic liquids, such as their multitasking, toxicity, thermal stability and solubility in water in comparison with commercial chemicals. Readers will find in the article the prospects for the use of ionic liquids in agriculture, as well as the high value of using ILs as multifunctional biologically active substances.

Synthesis of 3-chloro-N,N-diethyl-N-(2-(mesitylamino)-2-oxoethyl)propan-1-aminium iodide (1) was performed by via N-alkylation in conventional conditions and using microwave irradiation and ultrasound activation. The synthesized ionic compound was characterized using IR, 1H and 13C NMR, growth-stimulating activity had been tested for ten varieties and hybrids of sweet sorghum seeds.

A study of myelostimulating activity of ionic compounds-trimecaine alkyl iodide derivatives under the cipher BIV (BIV-117, BIV-118, and BIV-119) was conducted on a model of doxorubicin pancytopenia in white laboratory rats. It was established that the compounds BIV-117 and BIV-119 had a pronounced leukopoiesis-stimulating activity, exceeding the activity of the methyluracil as a comparison drug. Compounds BIV-117 and BIV-119 had erythropoiesis- and thrombocytopoiesis-stimulating activity at the level of methyluracil.
