Aim of study: The use of composites obtained from wood and similar lignocellulosic plants has increased all over the world. Because of the rapid depletion of forest natural resources, the rational use of declining wood raw materials and to evaluate environmental alternatives has gained importance. For this purpose, many alternative lignocellulosic raw materials are used as heat insulation material by producing foams.
Materials and methods: This research compared the properties of liquefied using cotton burr after liquefaction under different acid concentrations, PEG 400-Glycerin/Cotton burr ratios, pore sizes, and PEG 400/Glycerin ratios. The cotton burrs were put in a reaction chamber at 160 °C for 2 h with the PEG 400-Glycerin/cotton burr and sulfuric acid in a glass balloon.
Main results: The maximum yield in the liquefaction of cotton burrs was found in the polyethylene glycol/glycerin ratio of 1:1. It has been found that the amount of unliquefied cotton burrs decreased with increasing of the acid concentration, reaction temperature and time.
Research highlights: Consequently, the liquefaction of cotton burrs could be seamlessly used in the production of polyurethane-type foam.

Çalışmanın amacı: Odun ve benzeri lignoselülozik bitkilerden elde edilen kompozitlerin kullanımı tüm Dünya’da artmıştır. Orman doğal kaynaklarının hızla tükenmesi nedeniyle, azalan odun hammaddelerinin rasyonel kullanımı ve çevresel alternatiflerin değerlendirilmesi önem kazanmıştır. Bu amaçla, birçok alternatif lignoselülozik hammaddeden köpük üretilerek ısı yalıtım malzemesi olarak kullanılır.
Materyal ve yöntem: Bu araştırmada, pamuk kozaları farklı asit konsantrasyonları, PEG 400-Gliserin/Pamuk koza oranları, gözenek boyutları ve PEG 400/Gliserin oranlarında sıvılaştırılarak sıvılaşmanın özellikleri karşılaştırılmıştır. Pamuk kozaları, bir cam balon içerisinde PEG 400-Gliserin/pamuk kozası ve sülfürik asit ile 2 saat boyunca 160 °C sıcaklıkta bir reaksiyona tabi tutulmuştur.
Temel sonuçlar: Pamuk kozalarının sıvılaştırılmasındaki en iyi sonuç, polietilen glikol/gliserin (1: 1 oranı) ile belirlenmiştir. Asit konsantrasyonunun, sıcaklığın ve zamanın arttırılması ile sıvılaştırılmamış pamuk kozalarının miktarında bir düşüş olduğu tespit edilmiştir.
Araştırma vurguları: Sonuç olarak, pamuk kozalarının sıvılaştırılması, poliüretan tipi köpük üretiminde kullanılabilir olmasının uygun olduğu kanaatine varılmıştır.
