Synthesis of vanillin propylene glycol acetal over different molecular sieve catalysts was written by Wang, Wen-lan;Huang, Yong;Meng, Qing-lei;Liu, Bai-jun. And the article was included in Huaxue Gongchengshi in 2009.Name: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol This article mentions the following:
The vanillin 1,2-propylene glycol acetal was synthesized using vanillin and 1,2-propylene glycol as starting materials and HZSM-5, HY, H beta, HMCM-22, HMCM-41 different type mol. sieve as the catalyst. The catalysts were characterized by means of N2 adsorption-desorption and FT-IR of adsorption pyridine. The results indicate that the HMCM-22 mol. sieve has the higher activity and the each kind of mol. sieve active order is: HMCM-22 > H beta > USY > HY > HZSM-5 > HMCM-41. The higher activity was due to the large secondary pore structure of HMCM-22 mol. sieve and the suitable acidity. In the experiment, the researchers used many compounds, for example, 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (cas: 68527-74-2Name: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol).
2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol (cas: 68527-74-2) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Name: 2-Methoxy-4-(4-methyl-1,3-dioxolan-2-yl)phenol
