This study presents a new group of herbicidal ionic liquids (HILs) based on a cation occurs commonly in nature?acetylcholine. The HILs were obtained with a high yield through ion exchange between acetylcholine chloride and potassium or sodium salts of selected acids with herbicidal activity. The results of the herbicidal activity measurement against common oilseed rape (Brassica napus L.) exceeded those of the commercial products. Spray solutions of the synthesized HILs revealed high surface activity and wetting properties which further manifested as higher herbicidal activity. The reduction of surface tension and low contact angles together with the specific action of acetylcholine allowed for better penetration of synthesized HILs into plant tissues. In addition, OECD 301F tests confirmed high mineralization of the HILs. The simple transformation of commercial herbicides into acetylcholine HILs proved to be a very effective method of increasing their activity, and constitutes an interesting solution to the problem of weed infestation with the use of a substance commonly found in nature.

A simple, inexpensive, one-step general procedure was developed for the preparation of medium-chain fatty acid (MCFA) metal salts. This approach offers the advantage of a practical route and is superior to literature methods. Also, it overcomes many of the limitations previously reported for the preparation of fatty acid salts. The potential utility of this method is illustrated by the production of pilot-scale quantities of high-purity (>99.9%) sodium decanoate.
