NOT Necessary Evil og Benefit  [c.945]

This presentation will highlight some NDT applications whereby NDT can be transformed from a "necessary evil" into a situation that is "of beneficial value" to the user. From an activity that has to be done because it is required by the code, to a solution to a problem that can improve safety, enhance quality and save money.  [c.945]

In this way NDT can turn from a necessary evil, which it is too often still regarded to be, into a benefit.  [c.951]

Carbon disulphide is a volatile, evil-smelling liquid, although if carefully purified, the unpleasant smell is removed, as it is due to impurity. The vapour is inflammable and can form explosive mixtures in air  [c.201]

The evil>smelling residue in the reaction flask is best removed by the cautious addition of concentrated nitric acid.  [c.306]

Evil chemist "Uh, yes, this is Fake Name calling for Fake Company Name and I need to order some items or possibly open an account."  [c.12]

Evil "No. we used to have an account with Rival Scientific Company but they couldn t seem to get our orders on time."  [c.12]

Evil "Fake Company Name, at Address Of A Friend s House."  [c.12]

Drying isn t absolutely necessary, but it is a good bet that if a recipe stresses its use then an evil underground chemist will do so.  [c.29]

The last thing to remember is that the more HBr one packs into that acetic acid, the greater and quicker the yield will be. 70% HBr is still the paragon and should be strived for always. So with the proper HBr solution in hand the evil chemist can proceed with the conversion of safrole.  [c.145]

Carboxyl and nitrile groups are usually introduced in synthesis with commercial carboxylic acid derivatives, nitriles, or cyanide anion. Carbanions can be carboxylated with carbon dioxide (H.F. Ebel, 1970) or dialkyl carbonate (J. Schmidlin, 1957).  [c.49]

A simple example is the formation of the hydrogen molecule from two hydrogen atoms. Here the original atomic energy levels are degenerate (they have eipial energy), but as the two atoms approach each other, they interact to form tw u n oiuiegcn crate molecular orbitals, the lowest of which is doubly occupied.  [c.49]

Evalii atm g average distances, angles, and torsion angles, pins their deviations, can facilitate understanding of detailed molecular properties and functional characteristics.  [c.87]

Therefore the viscoelastic extra stress acting on a fluid particle is found via an integral in terms of velocities and velocity gradients evalua ted upstream along the streamline passing through its current position. This expression is used by Papanastasiou et al. (1987) to develop a finite element scheme for viscoelastic flow modelling.  [c.89]

Dissolve (or suspend) 0-25 g. of the acid in 5 ml. of warm water, add a drop or two of phenolphthalein indicator and neutralise carefully with ca. N sodium hydroxide solution. Then add 2-3 drops of ca. O lN hydrochloric acid to ensure that the solution is almost neutral (pale pink colour). (Under alkaline conditions the reagent tends to decompose to produce the evil-smelling benzyl mercaptan.) If the sodium salt is available, dissolve 0-25 g. in 5 ml. of water, and add 2 drops of ca. 0 -hydrochloric acid. Introduce a solution of 1 g. of S-benzyl-iso-thiuro-nium chloride in 5 ml. of water, and cool in ice until precipitation is Dibasic and tribasic acids will require 0-01 and 0-015 mol respectively.  [c.363]

Consider trans-C2H2Cl2. The vibrational normal modes of this molecule are shown below. What is the symmetry of the molecule Eabel each of the modes with the appropriate irreducible representation.  [c.361]

So anyway, that was what Strike told everybody in the first edition. People then ran with the idea and came up with some very interesting observations of their own since then, The following is an account of the PdCl2 method contributed by our good friend TDK. From what Strike knows of TDK she seems to be a very accomplished, careful and intuitive chemist in her own right. Nothing illegal of course. But she always seems to be coming across evil methodologies that others produce.  [c.65]

With all of that MD-P2P and/or P2P lying around, there s a good possibility that an evil underground chemist might turn it into final product. Dear God The thought of it just sickens Strike But what can ya do And what again were those final products Why it s these suckers right below  [c.97]

What the chemist has is an alcohol intermediate which is not what she wants. If she were to flick off that OH group then a double bond will form in its place and isosafrole or propenylbenzene will be borne [26], So what the evil chemist does is place 60g of the alcohol intermediate oil and 1g potassium bisulfate (KHSO4) into a really small flask, attach the flask to a distillation apparatus and start heating with vacuum. As the OH group is being kicked out it will form water, which the chemist will see distilling over. When no more water can be seen evolving then the reaction is finished. However, the chemist continues to heat to distill over all of the isosafrole which will smell just like licorice (yield=91% from the intermediate). If the chemist wanted to she could perform the same bisulfate procedure in a beaker or flask without the distillation setup and stop the reaction when a temperature of 170°C has been reached [28 p698]. The oil is still going to have to be distilled to purify it though.  [c.239]
