In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 105-30-6, name is 2-Methylpentan-1-ol, the common compound, a new synthetic route is introduced below. 105-30-6
Example 2 – Bis(2-methylpentyl) Octadecanedioate. [0129] Octadecanedioic acid (ODDA, 5.00 g) was added to a 100-mL three- necked round-bottom flask. A Dean-Stark condenser was attached, followed by the addition of toluene to the ODDA and to the trap. 2-Methylpentyl alcohol (5.90 mL) was added to the ODDA mixture. The flask was immediately purged with nitrogen gas and p-toluenesulfonic acid (0.17 g) was added. The reaction mixture was heated to 1 15 C and the reaction proceeded for 5 hours. Heat was then removed and the reaction mixture was allowed to cool to 60 C, at which point aqueous NaHC03 (saturated) was added to achieve a neutral pH. After vigorous stirring, the organic layer was separated and dried over Na2S04. The dried product was then subjected to a vacuum treatment to remove any residual solvent. A yellow oil was obtained. Analysis by 1H NMR provided the following chemical shifts: (400MHz, CDCIs) delta 0.90-0.85 (m), 1 .10-1 .20 (m), 1 .21 -1 .50 (m), 1 .55-1 .7 (t), 1 .77 (0), 2.30 (t), 3.85 (dd), 3.95 (dd). Anaylsis by 13C NMR provided the following chemical shifts: (400MHz, CDCI3) delta C 173.947; CH 32.366; CH2 69.200, 35.691 , 34.438, 29.701 , 29.684, 29.641 , 29.516, 29.319, 29.220, 25.095, 19.975; CH3 16.885, 14.258.
The synthetic route of 105-30-6 has been constantly updated, and we look forward to future research findings.
