In this paper, based on the theoretical analysis of the properties of ionic liquids dependence on their structure a number of compounds of this class with the optimal structure was synthesized for continuing the process of pretreatment of lignocelluloses raw material. The purpose of preprocessing is to remove lignin and hemicelluloses, as well as to reduce degree of crystallinity and increase the porosity of the cellulose, making it more accessible to the enzymes in the subsequent hydrolysis step in a process of production of bioethanol. As the optimal structures ionic liquids were proposed containing acetate and iodide anions.

Россия обладает огромными запасами различных природных ресурсов, к числу которых относятся и лесные ресурсы. Отходы от переработки древесины (щепа, опилки, ветки и кора деревьев, горбыль, костра и др.) являются ценным сырьем, но в настоящее время их использование ограничивается производством пеллет для получения тепловой энергии. Более глубокая переработка древесных отходов позволит получать значительно более ценные продукты: очищенную целлюлозу, лигнин, би-
