Inert oils

Use inherently safer chemistry (e.g., when phosgene is cooled in a heat exchanger, consider use of an inert oil as the coolant rather than water as heat exchanger tubes may fail)... 

Although most handbooks give its expin temp as 60°, more recent work (Ref 7) has shown that when 0,02g samples of NH4Mn04 were heated in air, they expld at 96° only after heating (induction period) for 600—700 seconds, while at 117° it required from 80 to 110 seconds. No exptn at 60° was reported. When smail samples were heated under confinement (immersed in an inert oil), they expld at 99.5° after about 10 minutes, but required 250 mins to expld at 70°... 

There have been two studies of the vacuum decomposition of NH4Mn04, the results of which differ in a number of important respects. Bircumshaw and Tayler s preparation [974] exploded in the temperature range 343—384 K unless reactant self-heating was reduced by immersion of the salt in an inert oil. Pavlyuchenko et al. [975] describe the reaction as slow between 343 and 363 K, very fast at >369 and explosive at... 

Syngas (typically a mixture of CO, H, and CO ) reacts over the active catalyst (Cu/Zn/AljOj) dispersed in an inert oil medium. This process offers considerable advantages over the conventional vapor phase synthesis of methanol in the areas of heat transfer, exothermicity, and selectivity toward methanol. However, this process suffers from the drawback that the methanol synthesis reaction is a thermodynamically governed equilibrium reaction. 

Polyaddition was also performed using chitosan stabilizer with two biocompatible costabilizers, Jeffamine D2000 and Gluadin, and a linking diepoxide in presence of an inert oil and it results, via an interface reaction, in thin but rather stable nanocapsules. Since both water and oil soluble aminic costabilizers can be... 

Paste electrodes - electrodes prepared by making a paste from an electron-nconducting material and a binder. The binder may be an electrolyte solution or inert oils like - Nujol. Paste electrodes can be part of batteries [i], where the electroactive material is used to prepare the paste, often with the addition of an inert electron conductor. In - electroanalytical chemistry, unmodified and modified - carbon paste electrodes are used. 

Observe normal precautions appropriate to the circumstances and quantity of material handled. Olive oil spills are slippery and an inert oil absorbent should be used to cover the oil, which can then be disposed of according to the appropriate legal regulations. 

Synthetic pump oils are also called inert oils. So far, there are mainly two types of synthetic pump oils available perfluoropoly ethers (PFPE) and... 

The methanol synthesis reaction and water-gas shift reaction take place over the coprecipitated Cu/ZnO/ AI2O3 catalyst, and the methanol dehydration reaction takes place over a y-alumina catalyst. The reactions are carried out at 250°C and 70 atm in a liquid phase involving inert oil, such as Witco-40, Witco-70, or Freezene-100 oil. 

If possible, it is preferable to use a higher volume fraction of the oil when compared with the suspension. In many cases, flocculation occurs more rapidly at higher solid volume fractions. The emulsion oil phase volume can be increased by the incorporation of an inert oil. 

Diluting the oil phase with another inert oil in which the particles are insoluble. The use of a strongly adsorbed polymeric surfactant such as Atlox 4913 or INUTEC SPl that prevents entry of the suspension particles into the oil droplets. 

Depot preparations are solutions of dmgs in inert oil allowing slow absorption... 

In 1975, Chem Systems developed the liquid phase methanol (LPMeOH) process which is based on the low pressure synthesis technology except that the new process is carried out in an inert oil phase [79], The catalytic system used is Cu/Zn0/Al203, that is modified for slurry operation (i.e., attrition resistant, finely powdered, and leaching resistant). The S3.85 and S3.86 catalysts of BASF and EPJ-19 and EPJ-25 catalysts of United Catalysts Inc. were developed for this process [14,19]. The process has been tested for commercial feasibility at a demonstration scale by Air Products and Chemicals, Inc [79]. 

Strain-rate dependence of ductility of the form shown in Fig. 7.81 is presented in Fig. 7.82 for a carbon steel in a carbonate-bicarbonate environment (Ref 119). The ductility is represented as the ratio of the reduction in area (RA) in the environment relative to the value in inert oil. The tests were conducted at the indicated constant potentials and illustrate that the strain-rate dependence can be sensitive to the potential, particularly the minimum ductility and the strain rate at which the minimum occurs. It follows, as an illustration, that if small changes in the environment, such as dissolved oxygen, shift the potential from -720 to -680 mV (SHE), significant changes in susceptibility to SCC would be predicted. 

Many antibiotic formulations are given in feed and as many antibiotics have allergenic properties, problems can arise in their use. Regulatory authorities now insist that such formulations are rendered dust-free by admixture with inert oils or by the production of granular formulations so that occupational exposure is minimized (76).

Colorless single crystals of P7[Si(SiMe3)3]3 suitable for X-ray diffraction (Fig. 3) analysis were grown in benzene. The data collection [4] was performed under a stream of N2 at -70°C using a Siemens diffractometer with a CCD SMART detector and graphite monochromated molybdenum K radiation (k = 0.71073 A). The crystal was mounted on the tip of a glass fiber in inert oil.
