Production details

The one-impression mould was made by Penton Tools Ltd of High Wycombe (part of the Guinness group). It is a conventional two-plate injection mould incorporating a side core to produce the front sliding cover channel. The mould was made from mild steel with hardened-steel cavity inserts. 

Elco Plastics Ltd of High Wycombe, Bucks, mould the TV screen surround on a Battenfeld BM 2 x 3200/500 S-C co-injection machine. That is, a 500 ton (5 MN) clamp force and two plasticizing cylinders each with 3200 cm swept volume capacity. The reciprocating screws in the plasticizing cylinders were 110 mm diameter with a L D ratio (length to diameter) of 15.5 1. 

Present-day cost of the machine is approximately 180 000 which is about 50% more expensive than a conventional compact injection-moulding machine of comparable size. 

Paste dispersions of blowing agents are reputed to produce mouldings with the most uniform cell structures.

In situ control and calibration of flare and other gas metering systems is performed by gaseous tracers using the transit time method without affecting the normal production. Details about methodology are given in / /. 

In some cases iinsaturated groups (carbon-carbon double bonds, carbonyl groups or nitriles) in close proximity to the carbon radical interact and give rise to abnormal products. Details will be discussed in the following sections. 

Despite the limited solubility of 1-octene in the ionic catalyst phase, a remarkable activity of the platinum catalyst was achieved [turnover frequency (TOP) = 126 h ]. However, the system has to be carefully optimized to avoid significant formation of hydrogenated by-product. Detailed studies to identify the best reaction conditions revealed that, in the chlorostannate ionic liquid [BMIM]Cl/SnCl2 [X(SnCl2) = 0.55],... 

Abstract A -Heterocyclic carbene complexes produced on industrial scale are presented in this chapter along with a discussion about their production. Details of processes employing NHC complexes on pilot to industrial scales are discussed. These are frequently oriented towards the synthesis of biologically active molecules, however, examples are given for rubber formation and for 1-octene synthesis, a comonomer for polyethylene synthesis. 

Figure 15 Conjugation of a carboxylic add and an amine using the carbodiimide method. The carbodiimide activates the carboxyhc acid to speed up the reaction to the amine. Carbodiimides can be used with nonpolar or polar solvents, including water. Undesirable urea complexes may form as by-products. Details of the reaction are given in Table 3...

Figure 17 Conjugation of an amine and a carboxyUc acid via the mixed anhydride method. Although the activated mixed anhydride is stable, it is usually used without purification. Use of low-temperature reactions will limit undesirable side products. Details of the reaction are given in Table 5...

DMBCOl), dimethylbicyclo[3.2.1]octanes (DMBC02), ethylsubstituted bicyclooctanes (EBCO) and trimethylbicycloheptanes (TMBCH). The last group consists of trimethylbicyclo[2.2.1]heptanes, trimethylbicyclo[3.1.1]heptanes and dimethylbicyclo[2.2.2]octanes. Some representative structures of the Iso groups are shown in Figure 2. Major cracking products (CP) were identified as cyclic hydrocarbons C5-C9 and isobutane. The main heavy products (HP) were methyl-and dimethyldecalins, or their isomers. No olefins and only traces of aromatics were found in the products. Detailed information about the product analysis is reported elsewhere (22).

The synthesis section systematically prepared new monomers, polymers, and an ever increasing number of copolymers. At the same time, the characterization and applications sections tested the polymers in order to ascertain which were worthy of larger scale experiments, scale-up, and patent protection. They also performed the work required to satisfy production details. These efforts, directed by Mark s personal hands-on style of management, were the first serious attempts at commercialization of polystyrene, poly(vinyl chloride), poly(methyl methacrylate), and synthetic rubber. 

Several large CROs have expanded their services into related markets such as contract product detailing, patient billing services and specialty pharmaceutical product development, manufacturing, and sales. The later situation can present a conflict of interest, if their own products are potentially competitive with the sponsor product candidates. Being both a CRO and a specialty pharmaceutical firm is awkward and represents an undesirable function in the contracting business. 

The Cs indicate the number of carbons in each intermediate and in the final products. Details of the pathway are presented in Figure 7.16, where the names of the enzymes are given. There are five important points, as follows ... 

Flame temperatures can be measured directly, using special high-temperature optical methods. They can also be calculated (estimated) using heat of reaction data and thermochemical values for heat of fusion and vaporization, heat capacity, and transition temperatures. Calculated values tend to be higher than the actual experimental results, due to heat loss to the surroundings as well as the endothermic decomposition of some of the reaction products. Details regarding these calculations, with several examples, have been published [5]. 

The industrial Nalco process for the production of 11a and 11b was conducted in mixtures of 53 with THF, at 35-40 °C or 40-50 °C and about 2 kg cm pressure, in a cell divided by porous diaphragms and with current densities of 1.5-3.0 A dm at 15-30 V. However, production details are beyond the scope of this Chapter. Effective methods of recovery of 11 from mixtures after or during the electrolysis were elaborated . Of...

Anionic polymerization has also been used to make telechelic polymers (Greek telos, end, and chele, claw), i.e., polymers with reactive terminal groups.We coined the term, telechelic in 1957 and it has been accepted ever since in technical as well as patent literature. Liquid carboxy- and hydroxy telechelic polybutadienes initiated with difunctional organolithium initiators are commercially produced since 1962. Some of the physical properties,production details and uses as in solid rockets... 

I11 dipolar aprotic solvents, the second step of the oxygen reduction is 02 -> 02 . However, if H+ is available from the solvent or from protic impurities, 02 reacts with H+ to form ()2I I or 02H2. Sometimes, the ()211 or 02H2 is further reduced at more negative potentials to give H20 as the final product. Detailed information concerning the electrochemistry of molecular oxygen can be found in Ref. [39 b].

Depending on the choice of processing conditions PPT fibres can be produced with significantly different mechanical performance. Perhaps the best known commercially available variants are Kevlar 29 and Kevlar 49 80). Although production details are confidential, it is probable that the latter has been subjected to a thermal treatment. 

In these later sections, interpretations of quantitative data for product mixtures are emphasised, and the relationship between kinetics and product analysis will be developed. Mechanistic applications of kinetic data are limited to steps of reactions prior to and including the rate-determining step. As separate later steps often determine the reaction products, detailed product studies and investigations of reactive intermediates are important supplements to kinetic studies. Examples of solvolytic and related (SN) reactions have been chosen first because they provide a consistent theme, and second because SN reactions provide an opportunity to assess critically many of the mechanistic concepts of organic chemistry. Product composition in solvolytic reactions will be discussed next followed by product selectivities (Section 2.7.2) and rate-product correlations (Section 2.7.3). 

Modifications are available to Apparatuses 1 and 2 that provide a low-volume vessel to increase the sensitivity of analysis for low-dose drag products. Details of this are discussed in the noncompendial equipment section.

The reaction of trimethylstannylsodium with two geminal dihalides, 6,6-dichloro-5,5-dimethyl-1-hexene and 6,6-diiodo-5,5-dimethyl-l-hexene, gave evidence of a single electron transfer pathway. An initial electron transfer from MetSn- to the geminal dihalides leads to the haloradical (X ), which then serves as the precursor to all the reactions and products detailed in Scheme 37195.
