Usage

General Description

2,5-Di-Tert-Butylphenol is an organic compound considered a derivative of phenol. Characterized by two tertiary butyl side groups attached to the benzene ring, this substance appears as a white to light pinkish crystal or powder. It is widely used in the chemical industry, particularly for making antioxidants for synthetic rubber, jet fuels, and electrical insulator materials. 2,5-DI-TERT-BUTYLPHENOL can be toxic if ingested, inhaled, or comes into contact with the skin. Proper safety measures should be taken while handling this chemical.

Method for synthesizing tert-butylhydroquinone

The invention discloses a method for synthesizing tert-butylhydroquinone, and relates to tert-butylhydroquinone. The invention provides a synthesis method of tert-butylhydroquinone, and the method hasthe advantages of simple process and lower cost. The method comprises the following steps: 1) sequentially adding a catalyst sulfamic acid, a solvent toluene or xylene, tert-butyl alcohol, hydroquinone and 1, 4-dioxane into a heatable pressure-resistant reactor for reaction at 120-150 DEG C for 4-12 hours; 2) after the reaction is finished, adding ethanol, filtering to remove the catalyst sulfamic acid, and removing the solvent to obtain a crude product; 3) purifying the crude product obtained in the step 2) to obtain the product tert-butylhydroquinone. The defects that catalysts with high corrosivity are needed in the existing synthesis process, the process cost is high, the environmental pollution is serious, and the reaction selectivity is low are overcome.

Structural features and antioxidant activities of Chinese quince (Chaenomeles sinensis) fruits lignin during auto-catalyzed ethanol organosolv pretreatment

Chinese quince fruits (Chaenomeles sinensis) have an abundance of lignins with antioxidant activities. To facilitate the utilization of Chinese quince fruits, lignin was isolated from it by auto-catalyzed ethanol organosolv pretreatment. The effects of three processing conditions (temperature, time, and ethanol concentration) on yield, structural features and antioxidant activities of the auto-catalyzed ethanol organosolv lignin samples were assessed individually. Results showed the pretreatment temperature was the most significant factor; it affected the molecular weight, S/G ratio, number of β-O-4′ linkages, thermal stability, and antioxidant activities of lignin samples. According to the GPC analyses, the molecular weight of lignin samples had a negative correlation with pretreatment temperature. 2D-HSQC NMR and Py-GC/MS results revealed that the S/G ratios of lignin samples increased with temperature, while total phenolic hydroxyl content of lignin samples decreased. The structural characterization clearly indicated that the various pretreatment conditions affected the structures of organosolv lignin, which further resulted in differences in the antioxidant activities of the lignin samples. These results can be helpful for controlling and optimizing delignification during auto-catalyzed ethanol organosolv pretreatment, and they provide theoretical support for the potential applications of Chinese quince fruits lignin as a natural antioxidant in the food industry.
