Caratteristiche strutturali e fisiche. Il ciclopentene presenta una scarsa affinità in acqua, solubilizzandone solamente 400 ppm a 23 °C ed a sua volta essendo scarsamente solubile in essa; è invece completamente solubile nella maggior parte dei solventi organici quali dietil etere, etanolo, benzene ed etere di petrolio. Recommendation for (Z)-4-methyl-2-pentene usage levels up to: not for fragrance use. Use levels for FEMA GRAS flavoring substances on which the FEMA Expert Panel based its judgments that the substances are generally recognized as safe (GRAS). Pentenes are alkenes with chemical formula C 5 H 10.Each contains one double bond within its molecular structure. There are a total of six different compounds in this class, differing from each other by whether the carbon atoms are attached linearly or in a branched structure, and whether the double bond has a cis or trans form.
