Hydrogen Chloride-Organic Compound Systems. The solubihty of hydrogen chloride in many solvents follows Henry s law. Notable exceptions are HCl in polyhydroxy compounds such as ethylene glycol (see Glycols), which have characteristics similar to those of water. Solubility data of hydrogen chloride in various organic solvents are Hsted in Table 10. 

Interaction of 6,7-dichloroquinoline-5,8-dione with amides in ethylene glycol afforded oxazolo[4,5-g]quinoline-4,9-dione, a compound with activity against Gram-positive bacteria (no data) (90MI2). 

Some data concerning the activity of antifreeze chemicals are presented in Table 14-1. Inspection of Table 14-1 shows that there are two different types of antifreeze chemicals, that is, liquids that are miscible over the full range of concentration with water and salts, often salts which are soluble only to a certain amount. In the case of liquids, a mixture of 50% by weight with water is given. In the case of solids, the ethylene glycol forms with water an... 

Measure 1.0 mL of ethylene glycol using a clean 10-mL graduated cylinder and place the ethylene glycol into a test tube. Record the amount used in Data Table 1. Shake the test tube gently to mix the contents. 

Fig. 2.9.10 Maps of the temperature and of the experimental data. The right-hand column convection flow velocity in a convection cell in refers to numerical simulations and is marked Rayleigh-Benard configuration (compare with with an index 2. The plots in the first row, (al) Figure 2.9.9). The medium consisted of a and (a2), are temperature maps. All other random-site percolation object of porosity maps refer to flow velocities induced by p = 0.7 filled with ethylene glycol (temperature thermal convection velocity components vx maps) or silicon oil (velocity maps). The left- (bl) and (b2) and vy (cl) and (c2), and the hand column marked with an index 1 represents velocity magnitude (dl) and (d2).

Although less common than zinc chlorides, there has been much synthetic and structural work carried out on zinc bromide and iodide complexes. For example, the 1 1 adduct of N,N,N, A -tetramethyl-o-phenylenediamine with zinc bromide has been structurally characterized.630 The ion exchange properties of zinc bromide and iodide have been studied in ethylene glycol.631 The electrolytic behavior of zinc bromide in propylene carbonate has been studied and the conductance data shows the existence of dimers.632... 

Next, with a PEG sample having as an average molecular weight of 600, the yields of complexes with a-CD were measured as a function of the amount of PEG in the solution, and the results presented in Fig. 4 were obtained. It is seen that the yield initially increases linearly with the polymer amount and begins to level off at a molar ratio of about 2 1 (ethylene glycol a-CD). The saturation corresponds to the consumption of a-CD of more than 90%. Fig. 5 delineates the data obtained by varying the amount of a-CD and keeping that of PEG fixed. It also proves that the complex formation obeys the 2 1 stoichiometric ratio. Further support to this fact can be seen from the NMR spectra shown in...

Several polymer-related uses of brassylic acid (BA) have been investigated. For example, a BA/l,3-butanediol/lauric acid oligomer is an effective plasticizer for poljrvinyl chloride,[6] BA/ethylene glycol and BA/propylene glycol polymers function as polyester based polyurethane elastomers,[7] and BA has been patented as a cross-linker for glycidyl methacrylate copolymer powder coatings.[8] However, the most detailed studies have involved polyamides selected data from these studies are summarized in Table I. 

Concentration profiles for compound 67 are given in Figure 7. Although the relative effect of dispersion due to tidal flow and downstream movement due to the net river flow are not precisely known, it is clear from these data that compound 67 comes from a point source located near river mile 100. In fact, the company which produces the precursor alcohols (no. 68-70), the chemically related chlorinated ethylene glycol (no. 64) and the Cg-phenol (no. 38) discharges its effluent at river mile 104.

The quasi-linear relationship between the logarithm of the retention factor and volume fraction organic cosolvent in the mobile lase seems to be the general rule in RPC. However, special effects can ur to cause this rule to be violated. Marked deviation from linearity was observed by Melander et al. (158) with retention data o poiy(ethylene glycol) derive-...
