House account

The six largest multinational fragrance houses account for some 70% of total fragrance compound sales. Theirs is a legacy of a century of experience and a financial strength that can cope with the tens of millions of dollars expense each year in pure research and development required to keep ahead of the game. 

Among all electrical and electronic products, computer, TV and similar housings account for 59% of brominated FR sales, and printed wiring boards for 30%. Connectors and relays are responsible for 9% of sales, while wire and cable insulation and sheathing use only 2%. Epoxy and phenolic PCBs represent high volume sales. 

Titanium dioxide is extensively used for both house paint and artist s paint, because it is permanent and has good covering power. Titanium oxide pigment accounts for the largest use of the element. Titanium paint is an excellent reflector of infrared, and is extensively used in solar observatories where heat causes poor seeing conditions. 

Big name science houses and chemical manufacturers These include such names as Fisher, Baxter, VWR, Cole-Parmer, Alltech, Aldrich and Sigma. It is very hard to get a fledgling account with these giants, but if one can then the sky s the limit. Most chemists should be happy getting these companies products through the distributors.

The electric arc furnace process accounted for about 25% of the 1982 U.S. steelmaking capacity (14). Most of the raw material used for the process is steel scrap. Pollutants generated by the electric furnace process are primarily particulate matter and CO. The furnaces are hooded, and the gas stream containing the particulate matter is collected, cooled, and passed to a bag-house for cleaning. Venturi scrubbers and ESPs are used as control devices at some mills. Charging and tapping emissions are also collected by hoods and ducted to the particulate matter control device. 

Although the nature of the general polar effect suggested by Kamernitzsky and Akhrem " to account for axial attack in unhindered ketones is not clear, several groups have reported electrostatic interactions affect the course of borohydride reductions. Thus the keto acid (5a) is not reduced by boro-hydride but its ester (5b) is reduced rapidly further, the reduction of the ester (6b) takes place much more rapidly than that of the acid (6a). Spectroscopic data eliminate the possibility that in (5a) there is an interaction between the acid and ketone groups (e.g. formation of a lactol). The results have been attributed to a direct repulsion by the carboxylate ion as the borohydride ion approaches. " By contrast, House and co-workers observed no electrostatic effect on the stereochemistry of reduction of the keto acid (7). However, in this compound the acid group may occupy conformations in which it does not shield the ketone. Henbest reported that substituting chlorine...

Finally, if the boiler house is to be within an industrial complex and there is no adjacent residential development, the building need only be suitable for adequate weatherproofing of the plant and for maintenance. Alternatively, if it is sited adjacent or near to housing or offices then the building structure should take account of this. 

The hardware should be dedicated to the maintenance department, as they then have access to the maintenance programs as and when necessary. Systems are implemented whereby the software is loaded onto the company in-house hardware, which can lead to periods when access is limited by other demands on computer time (e.g. accounts departments). The ideal situation would be for the maintenance department to have their own computer, with the back-up facility provided by the in-house computer, thereby ensuring that copy is held. 

In 1910 the price of rubber was 2.88 a pound, world production was 94,000 tons, and wild rabber from Brazil accounted for 83,000 tons. In 1912 the price collapsed, and by 1932 a pound of rubber cost 25. In 1937 the world bought more than 1.1 million tons of mbber, less than 2% of which came from Brazil. The rabber cities of the Amazon became near ghost towns as the market for wild rabber vanished. The opulent opera house in Manaus had barely opened its doors when the curtain came down on the Brazilian rabber economy. 

Considering the failure of available log D methods to predict in-house data and taking into account that such data are usually generated just for a few fixed pH values, a number of companies started to elaborate in-house methods for log D prediction at fixed pH. Up to date several companies have reported development of such methods. For example, Cerep has developed methods to predict log D at pH 7.4 and 6.5 included in their Bio Print package [107], but details of their method are not pubhshed. HQSAR Tripos descriptors were used by Bayer to develop log D models at pH 2.3 and 7.5 using 70000 (qi =0.76, STD =0.60) and 7000 (qi =0.83, STD =0.67) compounds, respectively [108] however, again, no details of the approach were provided.
