Reaction potassium

Reduction of [Co(CO)4] by sodium or potassium in liquid ammonia proceeded according to the Eq. (26) (shown for the potassium reaction). [Pg.32]

Reed 332) has reported that reaction of ethylene oxide with the a,(a-dilithiumpoly-butadiene in predominantly hydrocarbon media (some residual ether from the dilithium initiator preparation was present) produced telechelic polybutadienes with hydroxyl functionalities (determined by infrared spectroscopy) of 2.0 + 0.1 in most cases. A recent report by Morton, et al.146) confirms the efficiency of the ethylene oxide termination reaction for a,ta-dilithiumpolyisoprene functionalities of 1.99, 1.92 and 2.0j were reported (determined by titration using Method B of ASTM method E222-66). It should be noted, however, that term of a, co-dilithium-polymers with ethylene oxide resulted in gel formation which required 1-4 days for completion. In general, epoxides are not polymerized by lithium bases 333,334), presumably because of the unreactivity of the strongly associated lithium alkoxides641 which are formed. With counter ions such as sodium or potassium, reaction of the polymeric anions with ethylene oxide will effect polymerization to form block copolymers (Eq. (80) 334 336>). [Pg.74]

The Elovich equation has been used to describe the kinetics of P04 sorption and desorption on soils and soil minerals (Atkinson et al., 1970 Chien and Clayton, 1980 Chien et al., 1980 Sharpley, 1983), potassium reactions in soils (Sparks et al., 1980b Martin and Sparks, 1983 Sparks and Jardine, 1984 Havlin and Westfall, 1985), borate dissolution from... [Pg.22]

Selim et al. (1976a) proposed a mathematical model for potassium reactions and transport in soils. Kinetic reactions were assumed to govern the transformation between solution, exchangeable, nonexchangeable (secondary minerals), and primary mineral phases of potassium shown in Fig. 9.3. [Pg.181]

CHEMICAL PROPERTIES combustible liquid forms dense soot stable under normal temperatures and pressures hazardous polymerization will not occur reacts with active metals such as aluminum, magnesium powders, sodium, and potassium reaction with strong bases and strong oxidizers FP (NA) LFL/UFL (6%. 15.5%) AT (460°C, 860°F) HC (NA) HF (-191.5 kJ/mol liquid at 25°C). [Pg.963]

Surprisingly, in several experiments carried out under a variety of conditions, formation of the / cyclohexyne derivative 19b from cyclohexene and la was never observed. This complex was prepared from cyclohexene with f(C5H5)2Co]/potassium. Reactions with this reagent usually do not proceed cleanly and generate a large amount of insoluble by-products. Nevertheless, separation of the products is usually less laborious, due to the absence of 3 and 4. As a second type of product, the tetranuclear /r4-alkyne cluster complexes 21 were formed in very low yield from the corresponding cycloalkenes and [(C5H5)2Co]/K. ° ... [Pg.380]

Summary The synthesis of a,(0-bis[tris(trimethylsilyl)silyl] alkanes was achieved by the reaction of ct,(0-ditosylalkanes with tris(trimethylsilyl)silyl potassium. Reaction of these with one equivalent of potassium /er/-butoxide resulted in clean formation of monopotassium silyl anions. Addition of another equivalent of the transmetallating agent led to the formation of the dipotassium compounds in cases where the alkyl spacer contained at least three methylene units. Partial hydrolysis of the dipotassium compounds induced an intramolecular reaction yielding a cyclic silyl potassium compound. [Pg.331]

Calcium is less reactive than lithium, sodium and potassium. The bubbles of gas that are given off displace the water in the test tube. When tested with a lighted splint, the gas gives a pop and so it is hydrogen. Students can also note that the water becomes milky and might be asked to think what this may mean in terms of solubility of the product formed. (The product of this reaction is less soluble than the products of the lithium, sodium and potassium reactions.) Universal indicator solution is added to the water to show that the product is alkaline. The equation for this reaction is ... [Pg.231]

The melting points of sodium and potassium reaction products with alumino-silicate refractories are given in Table 4. The melting points of the phases themselves are not indicative of the very low eutectic temperatures found in the system. For example, the lowest eutectic in the system Na20-AljOa-SiOj (Figure 5) is 732°C. [Pg.72]
