Propylene glycol: solvents, moisture, and can be completely dissolved in water of the polyol class. Because of its strong skin permeability, dissolved strength, in addition to moisturizing abilities, helps active ingredients penetrating. 翻译结果4复制译文编辑译文朗读译文返回顶部 ...
Propylene glycol (CAS 57-55-6) is a colorless, odorless, and viscous liquid. It has a basic structure consisting of two hydroxyl groups attached to a propylene backbone. This chemical is highly soluble in water, making it miscible in all proportions. It also exhibits low volatility and a lo...
important petrochemical raw materials, used in the production of Polyether, propylene glycol, surfactant, foaming agent, demulsifier, mineral processing agent, etc. production methodchloropropanol is generated from propylene, chlorine and water at atmospheric pressure and 60 ℃, and then saponified, cond...
Propylene oxide is used as an interme-diate in the production of polyether polyols and propyleneglycol; as a fumigant; in the production of adducts as ure-thane foam ingredients; in detergent manufacture; as acomponent in brake fluids. 3.6 Produe Method Propylene oxide is synthesized commercially...
In an example a -propylene glycol and monobromoacetic acid are dissolved in ethylene dichloride, and heated with a sulphuric acid catalyst water, solvent being distilled off and the latter recycled. The product may be used in plastic or herbicidal compositions (see Group VI).ALSO:a -Propylene ...
by dissolving and removing a resist region of a resist layer formed in the resist pattern, wherein the developer comprises a surfactant capable of increasing the dissolution of a resist in the resist region to be dissolved and removed, having a smaller dissolving-and-removing area on the surface...
Propylene glycol phenyl ether RF-PPh RF-PPh是一种的环保型高沸点有机溶剂。RF-PPh is an environment-friendly high boiling point organic solvent.由于其特殊的化学结构中具备两个强溶解能力的基团-醚键和羟基,因而它既能溶解憎水性化合物,又能溶解水溶性化合物,故有“万能溶剂”之称。Because of its unique...
propylene glycol is an intermediate of the fungicide difenoconazole. as a solvent, preservatives, pigments, antioxidants and other food additives insoluble in water can be dissolved in it, and then added into food, it has moisturizing and anti-freezing effects on food. China's regulations can be...
To gain further insights into the key *C3 intermediates for propylene production, we performed the electrochemical reduction of allyl alcohol, propionaldehyde, hydroxyacetone and propylene glycol by dissolving them in KOH + CsI electrolyte. The possibility of decomposition of these compounds in alkali...
