Organic stabilizers

Such substances as vaseline (added to nitroglycerine powders of the cordite type), castor oil and rosin are also capable of stabilizing powder. 

Brunswig [17] gives the following comparative figures based on the weight loss 

The systematic studies of T. Urbanski, Kwiatkowski and Miladowski [76] proved that the addition of an aromatic nitro compound distinctly enhances the stability of nitrocellulose and nitrocellulose powder. Thus, nitrocellulose containing 13.4% N which on heating for 5 hr at 120°C had pH=2.28 showed pH=2.89 on addition of 9 1% p-nitrotoluene, pH=3.17 on addition of 9.1 % 2,4-dinitrotoluene and pH=3.34 on addition of the same amount of a-trinitrotoluene. The same samples when heated in a constant volume (Tagliani test) gave at 134.5°C a pressure of decomposition 

The experiments summarized in Table 175 show the stabilizing action of nitro-naphthalene. Dinitro- and trinitronaphthalene also act in a stabilizing manner. On the other hand mixed nitramines such as tetryl are detrimental to stability.

Commercial tetrahydrofuran (Matheson, Coleman and Bell) is washed several times with 40% aqueous sodium hydroxide to remove peroxides and organic stabilizers and then dried over solid sodium hydroxide. The clear supernatant liquid is used without further purification. 

STABREX is easier and simpler to use compared to any other oxidant available for industrial water treatment. The product is pumped directly from returnable transporters (PortaFeed Systems)17 with standard chemical feed equipment. Previously, the only practical ways to apply bromine were to oxidize bromide solutions on-site with chlorine in dual liquid feed systems, or with one of the solid organically-stabilized bromine products applied from sidestream erosion feeders. The former is cumbersome and complex, and the latter is prone to dusting and difficult to control. Other oxidants require complex handling and feed of toxic volatile gases, unstable liquids, multiple-component products, or reactive solids. Simplicity in use results in reduced risk to workers and to the environment. 

Activated sludge is the most common biological treatment process because of the high rate and degree of organic stabilization possible. It is widely used in treating refinery wastewater [5]. 

An adaptation, where an organism stabilizes its physiological condition after exposure to a chemical, without any irreversible disruption of a biological system and without exceeding the normal capacities of its response, should be considered as an early, not yet adverse, effect, which later on might lead to an adverse effect and thus needs expert judgment in a case-by-case manner. 

Calculate the optimal hiring frequency for the situation of Figure 10.1 when (V, C, p) = (20, 0.1, 0.1), (10, 0.2, 0.1), and (10, 0.1, O.2.). In each case, consider whether n increases or decreases. Do these quantitative results match the qualitative discussion of the section regarding transaction costs and the formation of organizations versus confederations In other words, is organization stability increased or decreased as the value, transaction cost, and success probability increase and decrease ...

Stability. Length of time the organism or toxin will remain effective in the environment (also called viability for live organisms). Stability is affected by various environmental factors including temperature, relative humidity, atmospheric pollution, and sunlight. 

Although in many cases organic stabilizers are used to protect polyamides against photo-oxidation, in a recent study it was evidenced that a mixture of CuCl2 and KI has a far better long-term stabilizing efficiency than a HALS Stabilizer (HMW-HALS-2) [132],...
