application | 2, 3-dichlorotetrahydrofuran is similar to tetrahydrofuran. it is an organic solvent with a wide range of uses and can dissolve almost all polymers except polyethylene, polypropylene and fluororesin. it is especially suitable for poly-ethylene, poly-ethylene resin and styrene-butadiene rubber. In organic synthesis, 2, 3-dichlorotetrahydrofuran is often used as a solvent. In addition, 2, 3-dichlorotetrahydrofuran is required to be used as a binder. 2, 3-dichlorotetrahydrofuran is also used in the precision tape industry. The polymer tetramethylene ether glycol of 2, 3-dichlorotetrahydrofuran is the raw material for the synthesis of polychloro-nitrogen acid elastic fiber and polyurethane elastomer. |
Preparation | 2, 3-dichlorotetrahydrofuran was synthesized using sulfuryl chloride and tetrahydrofuran as raw materials and carbon tetrachloride as solvent. The optimized reaction conditions were as follows: tetrahydrofuran 1.4mol, sulfuryl chloride 1mol, carbon tetrachloride 50ml, the reaction was carried out at 65~75 ℃ for 1 hour, the yield reached 79.3℉, the purity of the product was 95.6℉ by gas chromatography analysis, and the chemical structure of the product was confirmed by IR, HNMR and GC-MS. |
