Özet:

 Due to their cost-effectiveness and environmentally friendly nature, deep eutectic solvents DESs hold great potential for applications in biomass conversion and the production of green chemicals. In this study, the delignification of the stone pine Pinus pinea L. cone was performed using seven different ternary deep eutectic solvents TDESs. TDES treatments of stone pine cone samples were carried out in a microwave for 30 min. at 150 C. The two-based components of TDESs were choline chloride ChCl - 1 mol and lactic acid LA - 9 mol. The formic acid FA  2 mol, boric acid BA  1 mol, acetic acid AA  2 mol, sorbitol S  1 mol, triethylene glycol TEG  2 mol, ethylene glycol EG  2 mol, and glycerol G  2 mol were used as third component of TDES. ChCl:LA:BA gave the lowest solid residue yield 57.90 and highest lignin purity 86.89. Klason lignin content of control was 35.08. The lowest lignin content 19.42 and highest delignification 68.89 were obtained with ChCl:LA:FA treatment. The lowest and the highest L values were obtained from ChCl:LA:BA and ChCl:LA:EG treatments with 21.76 and 37.36, respectively. This results showed that the third component of TDES affects the delignification efficiency of stone pine cone.

 Uygun maliyetli olmaları ve çevre dostu doğaları nedeniyle derin ötektik çözücüler DÖÇ, biyokütle dönüşümü ve yeşil kimyasalların üretimindeki uygulamalar için büyük potansiyele sahiptir. Bu çalışmada, Fıstık çamı Pinus pinea L. kozalaklarının delignifikasyonu yedi farklı üçlü derin ötektik çözücü ÜDÖÇ kullanılarak gerçekleştirildi. Fıstık çamı kozalağı örneklerinin ÜDÖÇ işlemleri mikrodalgada 150 Cde 30 dakika süreyle gerçekleştirildi. ÜDÖÇlerin iki bazlı bileşenleri kolin klorür ChCl - 1 mol ve laktik asittir LA - 9 mol. ÜDÖÇin üçüncü bileşeni olarak formik asit FA  2 mol, borik asit BA  1 mol, asetik asit AA  2 mol, sorbitol S  1 mol, trietilen glikol TEG  2 mol, etilen glikol EG 2 mol ve gliserol G - 2 mol kullanıldı. ChCl:LA:BA en düşük katı kalıntı verimini 57,90 ve en yüksek lignin saflığını 86,89 verdi. Kontrolün Klason lignin içeriği 35.08 idi. En düşük lignin içeriği 19,42 ve en yüksek delignifikasyon 68,89 ChCl:LA:FA işlemiyle elde edildi. En düşük ve en yüksek L değerleri sırasıyla 21,76 ve 37,36 ile ChCl:LA:BA ve ChCl:LA:EG işlemlerinden elde edildi. Bu sonuçlar, ÜDÖÇ ün üçüncü bileşeninin fıstık çamı kozalağının delignifikasyon verimini etkilediğini göstermiştir.
