Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

Applications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

ZnO/ionic liquid catalyzed biodiesel production from renewable and waste lipids as feedstocks [PDF]

, 2019
A new protocol for biodiesel production is proposed, based on a binary ZnO/TBAI (TBAI = tetrabutylammonium iodide) catalytic system. Zinc oxide acts as a heterogeneous, bifunctional Lewis acid/base catalyst, while TBAI plays the role of phase transfer ...

Saponification of Polyallyl Acetate

Kobunshi Kagaku, 1967
異なる重合度をもつアクリル酸メチルポリマー, ポリアクリル酸から誘導したポリアクリル酸メチル, およびポリアクロレインをそれぞれポリアリルアルコールに還元し, これらをアセチル化によりポリ酢酸アリル (PAAc) に変えた。さらに, 酢酸アリルのラジカル重合および異なる重合条件で得られたアリルアルコールポリマーのアセチル化によって, 低重合度のPAAc試料を製造した。得られたPAAc試料をアセトン-水 (容積比で8: 2) 混合液中で, 水酸化カリウムを触媒に用いてケン化した。ケン化の初期速度定数はポリマーの重合度に依存したが, その後の段階における速度定数はすべての試料についてほぼ同じであった。PAAcのケン化反応におけるケン化の進行に伴う見かけの速度定数の増大, いわゆる反応加速効果は ...
