Solvents aromatic hydrocarbons

Chlorinated paraffins are relatively inert and exhibit excellent resistance to chemical attack and are hydrolytically stable. They are soluble in chlorinated solvents, aromatic hydrocarbons, esters, ketones, and ethers but only moderately soluble in ahphatic hydrocarbons and virtually insoluble in water and lower alcohols. 

Acrylics are chemically resistant at room temperature to dilute acids, except hydrofluoric and hydrocyanic, all alkalis and mineral oils. They are attacked by chlorinated solvents, aromatic hydrocarbons, ketones, alcohols, ethers and esters [60].

The -modification as a rule evolves as a more coarse-grained material than the a-phase. It is prepared by milling the crude Copper Phthalocyanine Blue with salt in the presence of a crystallization stimulating solvent. Aromatic hydrocarbons, esters, or ketones are normally used.

For the synthesis of 6,12-dihydro-6-hydroxy-cannabidiol as the intermediate in accordance with the invention the starting materials are the readily available olivetol (formula II) and cis-p-menth-2-ene-l,8-diol (formula III). The reaction is performed in a suitable solvent, aromatic hydrocarbons such as benzene and toluene, halogenated hydrocarbons such as methylene chloride, chloroform, dichloroethane and trichloroethane, ethers such as diethylether, diisopropylether and tetrahydrofuran having proved to be suitable. Furthermore it is possible to use mixtures of the said solvents. Toluene, benzene, methylene chloride and chloroform are the preferred solvents for use in the method of the invention. 

Phenol has a low melting point, it crystallizes in colourless prisms and has a characteristic, slightly pungent odor. In the molten state, it is a clear, colourless, mobile liquid. In the temperature range T < 68.4 °C, its miscibility with water is limited above this temperature it is completely miscible. The melting and sohdification points of phenol are quite substantially lowered by water. A mixture of phenol and ca 10% water is called phenolum liquefactum, because it is actually a liquid at room temperature. Phenol is readily soluble in most organic solvents (aromatic hydrocarbons, alcohols, ketones, ethers, acids, halo-genated hydrocarbons etc.) and somewhat less soluble in aliphatic hydrocarbons. Phenol forms azeotropic mixtures with water and other substances. 

Short-chain (SCCPs), medium-chain (MCCPs), and long-chain (LCCPs) CPs all have industrial applications and similar environmental concerns. CPs are viscous, colorless or yellowish dense oils with low vapor pressures, except for those of long carbon chain length with high chlorine content (70%), which are solid. CPs are practically insoluble in water, lower alcohols, glycerol and glycols, but are soluble in chlorinated solvents, aromatic hydrocarbons, ketones, esters, ethers, mineral oils and some cutting oils. They are moderately soluble in unchlorinated aliphatic hydrocarbons [1].

Bovenzi et al. (1995) examined 21 patients (16 women, 5 men) with SSc or localized variants of scleroderma. A significant association was found between exposure to organic solvents (aromatic hydrocarbons) and SSc (3 men, 1 woman). Among the male subjects, an increased odds ratio for SSc was observed for exposure to organic solvents, silica dust, and hand-transmitted vibration. Exposure to solvents and other chemicals was associated, albeit not significantly, with SSc among the women.

The solubility test results are Usted in Table 3.2. These results are classified into three types soluble (O), strongly swollen (p), and insoluble (c). The PLA membranes are insoluble in 11 of 16 polar solvents (protic acids and alcohols) and 9 of 11 nonpolar solvents (aromatic hydrocarbons and paraffins), but soluble in 28 of 32 aprotic solvents (amines and esters). Therefore, aprotic polar solvents can be used for PLA membranes.
