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. 2612-28-4, name is 2-Propylpropane-1,3-diol, the common compound, a new synthetic route is introduced below. Recommanded Product: 2-Propylpropane-1,3-diol
3rd Step 2-Propyl-1,3-propanediol 17.4 g (147 mol) and the above 3-(4-trifluoromethylphenyl)propanal 20.0 g (98.9 mmol) were dissolved in toluene 200 ml, and PTS 1 g was added, and the mixture was refluxed with heating for 3 hours while removing water formed with Dien-Stark. The reactant was washed with a saturated sodium bicarbonate aqueous solution, and then with saturated sodium chloride aqueous solution, and dried over anhydrous magnesium sulfate, and the solvent was distilled off. The residue was purified by silica gel column chromatography (eluent: toluene), and recrystallized twice from ethanol to obtain 5-propyl-2-(2-(4-trifluoromethylphenyl)ethyl)-1,3-dioxane 10.8 g (35.7 mmol). The yield was 36.1% from 3-(4-trifluoromethylphenyl) propanal. 1H-NMR(CDCl3) delta(ppm): 7.41 (dd,4H), 4.41(t,1H), 4.18-4.00(m,2H), 3.41-3.16(m,2H), 2.88-2.70(m,2H), 2.14-1.80(m,3H), 1.35-0.81(m,7H)
The synthetic route of 2612-28-4 has been constantly updated, and we look forward to future research findings.
