1-Hexadecanol CAS 36653-82-4

The northwest region of my country is dry and less rainy and has a large amount of evaporation. The water storage project has lost a lot of water resources by evaporation. In order to study water resources protection measures in arid areas, the ratio of 1-hexadecanol to ethanol was 1:6, the ultrasonic treatment power was 6 kHz, the time was 25 min, and the water evaporation inhibitor was stopped for 10 s for each treatment 30 s. The effect is the best, and the 24-hour inhibition rate can reach 45.3%. After the inhibitor is applied to the water surface, the oxygen content of the water body is roughly the same as that of the water body under natural conditions, and it will not affect the growth of aquatic animals and plants. The inhibitor is of great significance for reducing the loss of water resources in arid areas, and can bring huge economic and social benefits.

The surface modification of 1-hexadecanol is based on maintaining the original special physical structure skeleton of silica microspheres, so that the surface is changed from densely hydrophilic silanols to hydrophobic alkyl chains, and the surface properties are changed from hydrophilic to hydrophobic. It is hydrophobic and improves the dispersion of silica particles in organic media, which can significantly expand the application range and improve the application effect of nano-silica in organic materials.

In recent years, asphalt compositions have been widely used in road paving. With the increasing requirements for road pavements, asphalt roads with excellent strength, flow resistance and wear resistance are required. Therefore, it is necessary to prepare asphalt roads with higher softening point, Asphalt compositions with high mechanical strength, such as elastic modulus, need to be improved with various copolymer modifiers.

The high and low temperature resistant asphalt of 1-hexadecanol modifier is made of base asphalt, styrene-butadiene rubber, powdered sulfur chloride, montmorillonite, linolenic acid, glycerin aqueous solution, and 1-hexadecanol as raw materials. The base asphalt is heated, then linolenic acid and powdered sulfur chloride, styrene-butadiene rubber and montmorillonite are added, the asphalt is modified, and then after high-speed grinding process, the glycerin aqueous solution and 1-hexadecanol modifier are added after uniform dispersion , and further modify its stability. Finally, the product can be obtained after cooling and post-development. The prepared modified asphalt product is not prone to delamination, and has a short processing flow, so it has a good application prospect.
