Propylene CAS 115-07-1 R1270 98% C3H6 Non Toxic Refrigerant
Propylene is a colorless, slightly sweet gas at room temperature.Molecular weight of 42.08, the liquid density of 0.5139 g/cm3 (20/4 ℃), gas density 1.905 (0 ℃, and 101325 pa, abs) freezing temperature 185.3 ℃, boiling point 47.4 ℃.It slightly narcotic, all decomposition under 815 ℃ and 101.325 kpa.Flammable, explosive limit of 2% ~ 11%.Insoluble in water, soluble in organic solvents, is a kind of low-toxic substances.Propylene is the basic raw material for three major synthetic materials, mainly used for the production of polypropylene, acrylonitrile, isopropanol, acetone and propylene oxide.

Used for preparing acrylonitrile, propylene oxide, acetone, etc.Used to produce many important organic chemical raw materials, synthetic resin, synthetic rubber and many fine chemicals.
A painting made with acrylic paint.Acrylic pigment is a new kind of painting pigment which is made of a kind of synthetic glue emulsion (including acrylate, methacrylate, acrylic acid, methacrylic acid, thickener, filler, etc.) mixed with color particles.Acrylic pigment appeared in the 1960s, the test proved that it has many advantages over other pigments: flexible film after drying, strong and wear-resistant, water resistant, corrosion resistant, anti-aging, no fading, no deterioration and peeling, the picture does not reflect light, easy to wash after painting, suitable for painting on shelves, indoor and outdoor murals, etc.It can be repeatedly stacked layer upon layer, drawing a thick feeling;Powder and appropriate amount of water can also be added, covering with similar gouache overlap, the picture level is rich and clear;For example, adding a large amount of water in the pigment can give the effect of watercolor and traditional Chinese painting, with layers of drying, halo, and transparent effect.Because the main adjustment of propylene pigment water content is very large, so it is more suitable to paint on the rough bottom surface that is easy to absorb water, such as cardboard, cotton cloth, wood, fiberboard, cement wall, linen and wool to the metal surface, stone wall, etc..For acrylic painting, you can use ordinary oil brushes, painting knives, Chinese brushes, watercolor brushes, board brushes, sponges, loofah loofah, etc.Mixing tray and brush wash multi - purpose non - absorbent ceramic, glass, enamel containers, to prevent cleaning not clean.Propylene pigment in the water evaporation after drying, so when painting to know the process, in order to make the brush contact natural, to achieve the desired effect.
The largest amount of propylene is the production of polypropylene, and propylene can be made into acrylonitrile, isopropyl alcohol, phenol and acetone, butanol and octanol, acrylic acid and its lipids, as well as propylene oxide and propylene glycol, epichlorohydrin and synthetic glycerol.
