Heptane
Manufactured by Sinopharm
Sourced in China
Heptane is an organic compound with the chemical formula C7H16. It is a colorless, flammable liquid that is commonly used as a solvent in various industrial and laboratory applications. Heptane has a high boiling point and is often used in applications where a stable, non-polar solvent is required, such as in the synthesis of organic compounds, in the extraction of certain chemicals, and in the preparation of samples for analytical procedures.

The MSQ aerogel monolith was synthesized by a sol-gel process followed by ambient drying in an oven at 40 °C for 12 h. For hydrolysis and polymerization, Methyltrimethoxysilane (MTMS, Aladdin, Shanghai, China, 98%) was added into a mix of hexadecyltrimethylammonium chloride (CTAC, Aladdin, 97%), methanol, and HCl solution, with vigorous stirring and an ice-bath for 30 min. Propylene oxide (PO, Sinopharm Chemical Reagent Co., Ltd., Shanghai, China, ≥99.5%) was then added as a gelation agent into the mixed solution and stirred for 2 min. The fabricated mix solution was closed and placed into an oven at 40 °C for the gelation process for about 40 min and a further aging process for 40 min. The gel was further solvent-exchanged with 2-propanol, hexamethyldisilane/n-heptane, and heptane (Sinopharm Chemical Reagent Co., Ltd., Shanghai, China, ≥99.5%) to eliminate CTAC and water. Finally, the solvent-exchanged gels were dried at 40 °C for 24 h to prepare the monolith of MSQ aerogel.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
