Abstract

Levulinik
asit, endüstrinin birçok farklı alanında kullanılan bir karboksilik asittir.
Tarım alanında pestisit ve gübre amaçlı olarak kullanılmaktadır ve ayrıca
kendine özgü karamel kokusu nedeniyle kozmetik sektöründe ve aromatik
özellikleri nedeniyle gıda sanayisinde kullanılır. Karboksilli asitler
genellikle endüstride fermantasyon işlemleriyle üretilir ve nihai ürün
konsantrasyonu sulu çözeltide yaklaşık % 10'dur. Asitin sulu çözeltiden
ayrılması için birçok farklı yöntem vardır. Bunlardan biri reaktif
ekstraksiyondur. Bu çalışmada, Tri-n-oktil fosfin oksit ve çevre dostu
solventler (Dietil süksinat + 1-Bütil-3-metilimidazolyum hekzafulorofosfat)
kullanılarak reaktif ekstraksiyon yoluyla sulu çözeltiden levulinik asidin
uzaklaştırılması amaçlanmıştır. Deneysel tasarım uygulanmış ve optimum deney
sonuçları hesaplanmış ve veriler ANOVA ile analiz edilmiştir. Deneysel çalışma
sonucunda maksimum ekstraksiyon verimliliği % 55.1 olarak bulunmuştur.
Ekstraksiyon verimliliği için bağımsız değişkenler arasındaki model denklemi
belirlenmiştir. Bu verilere göre, elde edilen R² değeri 0.9899
olarak hesaplanmıştır.

Experimental Design of Reactive Extraction of Levulinic Acid Using Green Solvents

Abstract

Levulinic
acid is a carboxylic acid used in many different areas of the industry. It is
used as pesticide and fertilizer in agriculture industry, and it is also used
in the cosmetic industry due to its unique caramel odor and in the food
industry due to its aromatic properties. Carboxylic acids are generally
produced in the industry by fermentation processes, and the final product
concentration is approximately 10% in aqueous solution. There are many
different methods for the separation of acid from an aqueous solution. One of
them is reactive extraction. In this study, it was aimed to remove levulinic
acid from aqueous solution by reactive extraction using Tri-n-octylphosphine
oxide and environmentally friendly solvents (Diethyl
succinate+1-Butyl-3-methylimidazolium hexafluorophosphate). The experimental
design was performed, and optimum experimental results were calculated, and
data were analyzed with ANOVA. As a result of the experimental study, the
maximum extraction efficiency was found as 55.1%. The model equation between
the independent variables for the extraction efficiency was determined.
According to these data, the obtained R² value was calculated as
0.9899.
