Kev Tshawb Fawb Daim Ntawv Thov CAS: 74305-48-9|4-PENTYLPHENYL 4-PENTYLBENZOATE, 97

Ua kua Crystalline Mixtures

4-Pentylphenyl 4-pentylbenzoate thiab lwm cov tshuaj muaj feem xyuam tau kawm ntau heev rau lawv lub luag haujlwm hauv kev tsim cov kua crystalline sib tov. Kev tshawb fawb tau pom tias cov tebchaw no tuaj yeem tsim ntau yam mesophases, suav nrog nematic, smectic A, thiab smectic C theem, uas yog qhov tseem ceeb rau cov kua siv lead ua kua thiab lwm yam kev siv kho qhov muag (Chruściel li al., 2007). Kev kawm ntawm cov tebchaw no pab kom nkag siab txog kev cuam tshuam ntawm cov qauv molecular ntawm thermal stability thiab theem tus cwj pwm ntawm cov kua crystalline sib tov.

Molecular Structure Analysis
