حركية تفاعل 2-ميتيل 1,5 بنتان ثنائي أمين مع الحمض الديميري الدسم C36

Abstract EN

Kinetic studies were carried out on the reaction between 2-Methyl 1,5 diaminopentane and dimeric fatty acids in melt phase.

The reaction was performed at 113, 130, 140, 155, and 164 ºC and followed by determining the acid value of the product .The polyamidation reaction was found to be of overall second order with an activation energy of 45.48 k cal⁄g mol up to (52, 57, 79, 80, 86)% conversion at (113, 130, 140, 155, 164) ºC and overall third order with an activation energy of 43.73 k cal⁄g mol above (52, 57, 79, 80, 86)% conversion at (113, 130, 140, 155, 164) ºC.

The Degree of Polymerization, Number Average Molecular Weight and Weight Average Molecular Weight have been calculated during different times, the relationships between the Degree of Polymerization, Number Average Molecular Weight, Weight Average Molecular Weight and the times are linear until (52, 57, 79, 80, 86)% conversion at (113, 130, 140, 155, 164) ºC.
