The lifetime of di-n-propoxymethane in the lower atmosphere will be controlled by its reaction with OH. For daytime [OH] 2.5 x 10 molecule cm", the lifetime is about 4 h. Possible end products include di-n-propyl carbonate, following OH attack at the central CH2 group, or CH3CH2CH20CH20CH=0 and acetaldehyde, following OH attack at the two equivalent CH2 groups adjacent to the ether site. 

Tetrachloro-5,6-diphenyl- and -5,6-di-n-propyl calicene were found to yield intensely colored radical anions when interacted with alkali metals (Na, K)291. As ESR-spectroscopic investigation showed an unpaired electron spin is located on three-ring carbons Cs/C6 and their substituents.

The reaction proceeds via the formation of the palladacycles 4 and 7a. After the formation of 29 by 6-propylation of 31, elimination of j6-carbon regenerates nor-bomene (1) and 2,6-dipropylphenylpalladium bromide 30. At the final step, Suzuki coupling of 30 with 27 gives 2,6-di-n-propyl-1-biphenyl (28) in a surprisingly high yield (95 %) after so many steps [8].

Peroxydicarbonates. Peroxydicarhonates, such as di-(n-propyl) peroxydi-carbonate and di-(sec-butyl) peroxydicarbonate, are relatively expensive products used largely to initiate polymerization of PVC.

Successful results have been obtained (Renfrew and Chaney, 1946) with ethyl formate methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl and iso-amyl acetat ethyleneglycol diacetate ethyl monochloro- and trichloro-acetates methyl, n-propyl, n-octyl and n-dodecyl propionates ethyl butyrate n-butyl and n-amyl valerates ethyl laurate ethyl lactate ethyl acetoacetate diethyl carbonate dimethyl and diethyl oxalates diethyl malonate diethyl adipate di-n-butyl tartrate ethyl phenylacetate methyl and ethyl benzoates methyl and ethyl salicylates diethyl and di-n-butyl phthalates. The method fails for vinyl acetate, ieri.-butyl acetate, n-octadecyl propionate, ethyl and >i-butyl stearate, phenyl, benzyl- and guaicol-acetate, methyl and ethyl cinnamate, diethyl sulphate and ethyl p-aminobenzoate. 

Compounds which dissolve in concentrated sulphuric acid may be further subdivided into those which are soluble in syrupy phosphoric acid (A) and those which are insoluble in this solvent (B) in general, dissolution takes place without the production of appreciable heat or colour. Those in class A include alcohols, esters, aldehydes, methyl ketones and cyclic ketones provided that they contain less than nine carbon atoms. The solubility limit is somewhat lower than this for ethers thus n-propyl ether di olves in 85 per cent, phosphoric acid but n-butyl ether and anisole do not. Ethyl benzoate and ethyl malonate are insoluble. 

The photodecomposition of perfluoro diethyl-62 and perfluoro-di-w-propyl63 ketones has been shown to follow a course similar to that of hexa-fluoroacetone. The fluorescence is weaker in the case of the perfluoro-diethyl ketone and almost absent in the case of the perfluorodi-n-propyl ketone, and the pressure dependence of the quantum yields of carbon monoxide is consistent with this behavior. It is proposed that in the more complex structures, the energy may more easily be accommodated and lost by internal conversion, thereby reducing the contribution made by fluorescence and by Collisional quenching of the excited molecule. 

Magadiite apart from pentasil phases can be found in zeolites synthesized with mono-n-methy1-, -ethyl-, -propyl- or -butylamine, with di-n-methyl-, -ethyl- or -propylamine, with tri-n-methyl- or -ethylamine and with tetramethylammonium iodide. Table IV shows that the zeolite content increases with the number of carbon atoms per group and with the number of alkyl groups. 

Carbon-carbon bond scission is rather unimportant in diethyl ether (< 0.5%) and methyl n-propyl ether (< 2%), but is enhanced somewhat in t-butyl methyl ether (= 4.5%) and di-t-butyl ether (7%). The reverse has been found regarding the formation of hydrogen.
