Cyclopentanon Verwendung<\/strong><\/h2>\n

1. Unter Verwendung von Cyclopentanon und n-Valeraldehyd als Rohstoffe wird zun\u00e4chst eine Aldolkondensation und dann eine Dehydratisierung durchgef\u00fchrt, um Pentylcyclopentanon zu erzeugen, gefolgt von einer selektiven katalytischen Hydrierung, um Pentylcyclopentanon zu erzeugen, das stark ist. Es hat einen blumigen und fruchtigen Duft und riecht nach Jasmin. Es kann in t\u00e4glichen chemischen Duftformulierungen verwendet werden. Die Dosierung kann weniger als 20% betragen. Die IFRA hat keine Einschr\u00e4nkungen.<\/h4>\n

2. Unter Verwendung von n-Hexanal und Cyclopentanon als Rohstoffe werden sie zun\u00e4chst kondensiert und dann selektiv hydriert, um Hexylcyclopentanon zu erhalten. Hexylcyclopentanon hat einen starken Jasminduft und einen fruchtigen Duft, der in Parf\u00fcmd\u00fcften verwendet werden kann. Und in verschiedenen anderen t\u00e4glichen chemischen Geschmacksformeln liegt die Dosierung innerhalb von 5%. Die IFRA hat keine Einschr\u00e4nkungen.<\/h4>\n

3. Das durch Pyrolyse von Paraffin oder Dehydratisierung des entsprechenden Alkohols gewonnene 1-Penten oder 1-Hepten wird als Ausgangsmaterial verwendet und in Gegenwart von Di-tert-butylperoxid als Initiator einer radikalischen Additionsreaktion mit Cyclopentanon unterzogen, um 2-Pentylcyclopentanon (oder 2-Heptylcyclopentanon) zu bilden, das nach der Ringerweiterung durch Oxidation zu \u03b4-Decanolacton (oder \u03b4-Laurolacton) wird.<\/h4>\n

4. Der Syntheseweg mit Cyclopentanon als Ausgangsstoff hat den gr\u00f6\u00dften industriellen Produktionswert. Cyclopentanon wird zun\u00e4chst einer Aldolkondensation mit n-Valeraldehyd unterzogen, das Kondensationsprodukt wird nach Dehydratisierung und selektiver Hydrierung zu 2-Pentylcyclopentanon und schlie\u00dflich nach oxidativer Ringerweiterung zu \u03b4-Decanolacton.<\/h4>\n

5. Delta-Decanolacton wird haupts\u00e4chlich in essbaren Geschmacksformulierungen verwendet. Es soll den charakteristischen Geschmack von nat\u00fcrlicher Sahne haben. Zuvor waren die Parf\u00fcmeure lange Zeit darauf beschr\u00e4nkt, monomere Duftstoffe wie Diacetyl und Vanillin als Hauptrohstoff f\u00fcr die Formulierung von Sahnearomen zu verwenden. Die Menschen haben jedoch im Allgemeinen das Gef\u00fchl, dass das zubereitete Sahnearoma den nat\u00fcrlichen Produkten in Bezug auf Geschmack und Aroma weit unterlegen ist. Nur wenn \u03b4-Decanolacton verwendet wird, kann es einen lebendigen Sahnegeschmack haben, besonders wenn \u03b4-Decanolacton und \u03b4-Laurolacton zusammen als Hauptduftrohstoffe verwendet werden, werden der Geschmack und die Wirkung des formulierten Sahnegeschmacks besser sein.<\/h4>\n

6. Nehmen Sie Cyclopentanon und Valeraldehyd als Rohstoffe, kondensieren Sie, um 2-(1-Hydroxy)pentylcyclopentanon zu erzeugen, reagieren Sie mit Dimethylmalonat, und dann hydrolysieren, decarboxylieren und verestern Sie bei 160\uff5e180\u2103 , Man erh\u00e4lt Dihydrojasmonatmethylester. Dihydrojasmonatmethylester ist ein Lebensmittelgew\u00fcrz, das nach GB2760-1996 in meinem Land vor\u00fcbergehend verwendet werden darf. Sein Aroma ist besser als das von nat\u00fcrlichem Methyljasmonat und seine Eigenschaften sind relativ stabil.<\/h4>\n
