Line cord. Brings a.c. power to unit. Should be plugged into a live wall socket [See J. E. Leonard and L. E. Mohrmann, J. Chem. Educ., 57,119 (1980), for a modification in the wiring of older units, to make them less lethal. It seems that even with the three-prong plug, there can still be a shock hazard. Make sure your instructor knows about this ]. 

We haven t discussed activities, vapor pressure and other aspects of the thermodynamics of liquids (optimistically assuming you ve done all this in P. Chem). Nevertheless, we are sure that you recall that the vapor pressure of the solvent in a polymer solution relative to the vapor pressure of the pure solvent may, to a first approximation, be equated to the activity of the solvent, which in turn is related to the chemical potential by ...

There are many good ways to draw these conformations and yet more not quite so good. Make sure ou have each acetal oxygen atom axial on the other ring to enjoy the full anomeric effect op. 1128-31). We show three ways to draw each compound. The natural products are, in fact, the impounds in the frames according to R. Baker et al, ]. Chem. Soc., Chem. Commun., 1982, 601. 

Let me tell ya, folks. It sure is easy to talk to U.S. chem companies after you tell em you re from another country. They had absolutely no interest as to what my intentions were or whether my company had bank credentials or DBA permits. Nothing Like their U.K. and Aussie counterparts, some U.S. companies thought it odd that someone would go overseas to get these things but none (I mean absolutely zero) of the companies had a problem sending anything to anyone in any other country. 

As it turns out this guy is an ex-nuclear chemist so we start rapping about chems. I pointed out to him that about half of all the chems listed in the Merck Index give photography as a principal use so why in the hell aren t they here in his store He said that with the refinement of premade solutions no one has need of basic chemicals. Surely some purists still require the stuff, 1 say. But he said he never heard of such a thing. Before 1 left I asked him if he could special order any chems from the Eastman-Kodak fine chemicals division but he said he couldn t.

As referred to in the previous section, the large body of information contained in the protein data bank, together with proprietary protein structure databases, is now enabling extremely comprehensive analyses of molecular interactions. In the 2011 volume of J. Med. Chem. Stahl et al. provide a superb overview of molecular interactions of importance to drug designers, which has been assembled through analysis of such databases. The quality of such scholarship can surely only enhance the design skills of those who study this compilation.

Sodium bis(trimethylsilyl)amide (hexamethyl disilazane sodium salt) [1070-89-9] M 183.4, m 165-167 (sintering at 140"). It can be sublimed at 170"/2mm (bath temperature 220-250") onto a cold finger, and can be recrystallised from C i (its solubility is lOg in 100ml at 60"). It is slightly soluble in Et20 and is decomposed by H2O. [Wannagat Niederpriim Chem Ber 94 1540 7967.] It is available commercially under N2 in Sure/Seal bottles in tetrahydrofirran (various concentrations) and at 0.6M in toluene.
