Synthesis of liquid crystal containing C2 bridge of 1,1-difluoroethane or ethyne group was written by Chen, Xin-bing;An, Zhong-wei. And the article was included in Yejing Yu Xianshi in 2003.HPLC of Formula: 39969-26-1 This article mentions the following:
Liquid crystal containing C2 bridge of 1,1-difluoroethane or ethyne group were synthesized by an improved method with overall yield 26% and 39%, which are very important materials used in TN, STN, TFT liquid crystal composition The structures of the compounds are confirmed by IR, 1H NMR. In the experiment, the researchers used many compounds, for example, 1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1HPLC of Formula: 39969-26-1).
1-Methoxy-4-((4-propylphenyl)ethynyl)benzene (cas: 39969-26-1) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.HPLC of Formula: 39969-26-1
