“…As a result of isomerization performed at the temperature of 65 • C, a mixture of the following products was obtained: α-terpinene, γ-terpinene, terpinolene, and p-cymene. At this temperature the conversion of limonene achieved 38% after the reaction time of 60 min [23].…”

Abstract:The isomerization of limonene over the Ti-SBA-15 catalyst, which was prepared by the hydrothermal method, was studied. The main products of limonene isomerization were terpinolene, α-terpinene, γ-terpinene, and p-cymene-products with numerous applications. The amount of these products depended on reaction time, temperature, and catalyst content. These parameters changed in the following range: reaction time 30-1380 min, temperature 140-160 • C, and catalyst content 5-15 wt %. Finally, the most favorable conditions for the limonene isomerization process were established: a reaction time of 180 min, temperature of 160 • C, and amount of the catalyst 15 wt %. In order to obtain p-cymene (dehydroaromatization product), the most favorable conditions are similar but the reaction time should be 1380 min. The application of such conditions allowed us to obtain the highest amounts of the desired products in the shortest time.

“…A large choice of acidic catalysts, such as oxides treated with acids [14,15], modified zeolites [10,13,[16][17][18][19][20], activated clays [21] and heteropoly acids [22,23] have been suggested in the literature for the isomerization of ␣-pinene. On the other hand, basic catalysts (e.g., alkaline earth-metal oxides) have been reported for the isomerization of ␣-to ␤-pinene [24].…”

Only innovative products will be sustainable to open up new markets and new horizons for textile industry. As a response to consumer demand, in recent years textile manufacturers are demonstrating increasing interest in added value products by getting the insect repellents, cosmetics, antimicrobials, phase-change materials, fire retardants, counterfeiting, polychromic and thermochromic effects. Aromatherapy application in textile industry led to a series of value-added products that give besides comfort a number of other properties (anti-acne, antimicrobial, fragrance, anti-inflammatory sedation, or soothing properties). In recent years, aromatherapeutic textiles were applied in many fields such as food, cosmetics, medicine, tobacco, textiles, leather, papermaking and pharmaceutical industries. The purpose of this chapter was to present the essential oils used in textile finishing, textile supports used for aroma finishing, embedding methods and the controlled release of essential oils.
