Abstract: Compositions comprising 3-hexen-1-ol are described herein, as well as odor-imparting formulations comprising same and articles-of-manufacturing comprising such compositions or odor-imparting formulations. The compositions comprise trans-3-hexen-1-ol in a range of from 67% to 82% by weight and cis-3-hexen-1-ol in a range of from 18% to 33% by weight, wherein a total concentration of trans-3-hexen-1-ol and cis-3-hexen-1-ol is at least 97% by weight. Further described herein is a process for preparing a composition comprising 3-hexen-1-ol, the process comprising: contacting 1-pentene with a formaldehyde in the presence of a Lewis acid to thereby obtain a crude mixture comprising 3-hexen-1-ol; and contacting the mixture comprising 3-hexen-1-ol with a base.

Abstract: A system for releasing edible material is disclosed. The system comprises: a plurality of compartments adapted to receive a respective plurality of capsules, each capsule containing therein an edible material; a dispenser system configured for dispensing into an environment a fluid obtained from at least one edible material; and a controller configured for receiving data pertaining to a selection of at least two of the compartments and for signaling the dispenser system to dispense fluids obtained from edible materials contained in capsules of the selected compartments.

Abstract: A process of obtaining a purified geometric isomer of an unsaturated macrocyclic compound is disclosed herein. The process is effected by contacting an ion exchange medium comprising silver ions with a mixture comprising at least one geometric isomer of the unsaturated macrocyclic compound, to thereby obtain at least one fraction comprising the purified geometric isomer of the macrocyclic compound. A system configured for performing the process is also disclosed.

Abstract: A process of preparing 2-cyclohexyliden-2-phenyl acetonitrile or odoriferous structural analogs thereof, represented by Formula I: wherein the variables are as defined in the specification, is provided. The process utilizes a phase transfer catalyst, is performed at a temperature lower than 80° C., and provides odoriferous substances at a high yield and purity.

Abstract: A system for releasing flavor comprises: a plurality of compartments adapted to receive a respective plurality of capsules, each capsule containing therein a flavor material; a dispenser system configured for dispensing into an environment a fluid obtained from at least one flavor material; and a controller configured for automatically selecting a dispensing protocol, for signaling the dispenser system to dispense fluids obtained from at least one flavor material contained in at least one capsule of the compartments, and for automatically re-executing the selecting and the signaling, according to a shuffle protocol.

Abstract: A scenting concentrate and a formulation containing same, which imparts a long-lasting grass scent, is disclosed. Methods and systems utilizing the formulation for imparting a grass scent to a substrate such as artificial grass are also disclosed.
