The apparatus consists of a 2-1., three-necked, round-bottomed flask equipped with a mechanical stirrer, a pressure-equalized dropping funnel through which dry nitrogen can be added, and a reflux condenser, and is to be maintained at 0°. The outlet tube on the reflux condenser leads to a large U-tube trap, fitted with stopcocks on both sides, and immersed in a Dry Ice-isopropyl alcohol bath. The U-trap vents to a mineral oil bubbler. (See Fig. 17.) Sodium fluoride, 454 g. (10.8 mols) is added to the flask followed by approximately 1200 ml. of tetramethylene sulfone. The system is then flushed thor-... 

Inspection of Fig. shows that the formulas 19 and 20 as printed are identical. A difference becomes apparent only when they are considered in relation to the corresponding formulas (13 and 14), which indicate the origin of the electrons associated with thor n -systems. 

In mid-1959 the Minister of Defence, Sandys, on the advice of his permanent secretary, Powell, established an independent British Nuclear Deterrent Smdy Group, with representatives of the three services, the Foreign Office and the Treasury, under Powell s chairmanship. The group compared Blue Streak with two American ballistic missiles, the submarine-launched Polaris and the air-launched Skybolt. Rising estimates for the costs of research and development and of underground silos hardened the Treasury s opposition to Blue Streak, and the Chiefs of Staff were in favour of a mobile system. Once President Eisenhower had indicated to Macmillan in March 1960 that Skybolt would be available on satisfactory terms, the Defence Committee took the decision to cancel Blue Streak as a weapons system. The vulnerable Thors were taken out of service by the end of 1963.

Other most successful durable treatment is based on tetrakis (hydroxymethyl) phosphonium derivatives. Very well-known brand marketed as Proban CC (Rhodia, previously Albright Wilson) involves padding of tetrakis (hydroxymethyl) phosphonium chloride (THPC) urea solution onto the cotton fabric, curing with ammonia in a specially designed reactor to generate a highly cross-linked three-dimensional polymer network. The fabric is then treated with hydrogen peroxide, which converts P3+ to the P5+ state. The reactions are shown in Scheme 24.2. Other similar commercial product is Thor s Aflammit P. In literature many combinations of tetrakis (hydroxymethyl) phosphonium derivatives with other salts have been reported,50 but the most successful so far has been the THPC-urea-NH3 system discussed earlier.

The dominance of MDL in compound database management can be illustrated by pointing out that another company. Daylight Chemical Information Systems, which markets database management systems and compound databases, is mentioned in CJACS a total of five times. A Daylight software product called DAYMENUS is mentioned only once, and that was in 1992. THOR, the current name of the database management system, is cited in four papers.
