Case Study

Creation of Transparent Superhydrophobic Surfaces via Silicone Oil Combustion

Creation of Transparent Superhydrophobic Surfaces via Silicone Oil Combustion Seo, Kwangseok, Minyoung Kim, and Seunghwan Seok. Colloids and Surfaces A: Physicochemical and Engineering Aspects 492 (2016): 110-118.

Transparent superhydrophobic coatings can be easily created by using commercial silicone oil and controlling combustion. In this simple manufacturing process, silicone oil is sprayed onto heated glass at approximately 550 °C, resulting in the formation of a transparent superhydrophobic coating on the glass.
Transparent Superhydrophobic (TSH) Coating: To quickly cool and heat the sample, a gas furnace and a 4-inch silicon wafer are used as the heating plate. To measure the temperature of the heating system, a thermocouple thermometer is placed in direct contact with the wafer. The maximum temperature of the wafer plate is about 600 °C, which is sufficient to ignite the silicone oil. For the TSH coating, silicone oil is sprayed onto a hot glass slide heated to over 550 °C. The spray pump is positioned 15 cm away from the glass slide, with the spray angle set at 45° to the slide. Silicone oils of different viscosities are sprayed onto the glass, and after the silicone oil combusts, the glass slide is immediately removed from the heating plate.

Synthesis of Size-Controlled SiOC Ceramic Materials via Silicone Oil Emulsion Method

Synthesis of Size-Controlled SiOC Ceramic Materials via Silicone Oil Emulsion Method Seok, Eunjeong, et al. Journal of Alloys and Compounds 969 (2023): 172386.

A simple synthesis strategy using economical silicone oil as the starting material and employing the emulsion method, followed by pyrolysis of the silicone oil emulsion at 900 °C, successfully produced submicron spherical silicon oxycarbide (SiOC) materials for use as an anode in lithium-ion batteries.
Preparation of Size-Controlled SiOC (SC-SiOC): An oil-in-water (o/w) emulsion was prepared using the water phase and oil phase. First, to prepare the water phase, a 1M sodium hydroxide solution was made in distilled water to adjust the pH to 7, and chitosan (85% deacetylation) was stirred at room temperature overnight. Then, Tween 80 was added for dispersion. Next, as the oil phase, silicone oil was prepared with a weight ratio of one-third the amount of water phase. The silicone oil was added dropwise to the water phase under stirring to form the emulsion. The emulsion was then transferred to a quartz tube and subjected to pyrolysis at 900 °C for 1 hour under a 200 sccm argon gas flow. The powder was recovered from the quartz tube and named size-controlled SiOC (SC-SiOC).

Synthesis of 5,8-Difluoro-2H-Cycloheptene Using Silicone Oil as Solvent

Synthesis of 5,8-Difluoro-2H-Cycloheptene Using Silicone Oil as Solvent Kong, Jianshe, Tao Meng, and Jing Su. Organic Process Research & Development 19.6 (2015): 681-683.

A significantly improved synthesis method for 5,8-difluoro-2H-cycloheptene using silicone oil as the reaction solvent is described. The new method eliminates the cumbersome post-treatment and large amounts of waste generated by traditional methods.
Experimental Procedure: Under a nitrogen atmosphere, 710 g of compound 6 (4.22 mol) was dissolved in 7.5 L of silicone oil in a 12 L three-neck flask equipped with a mechanical stirrer. The solution was heated to 195 °C (internal temperature) for 18 hours using a heating mantle. After cooling the crude product, a sample was taken for 1H NMR analysis. The NMR spectrum showed 8% of the starting material. The crude product was then distilled through a 15 cm Vigreux column under 3-4 mmHg pressure into a receiver cooled to room temperature. The first fraction was collected at 75 °C (internal temperature, 115 °C external temperature, 4 mmHg), yielding 61 g of compound 1 (purity 91%, with 9% of the starting material based on 1H NMR). The main fraction of compound 1 was obtained at the same temperature (444 g, purity 94%, with 6% of the starting material). The third and final fraction (40 g of compound 1, purity 97%, with 3% of the starting material) was collected and combined with the main fraction. Except for the first fraction (recovered for the next round of reaction), 484 g of the desired product 1 was obtained as a colorless oily substance, with a yield of 68% and purity of 94%. The silicone oil was filtered through a 1 kg silica gel pad.
