ジャーナル フリーThe rates of hydrolysis reaction of 3, 4-dihydro-2 H-pyran-2-carboxaldehyde and 3, 4-dihydro-2 H-pyran-2-methanol catalysed by hydrogen ion were measured and it was found intrinsically the same as that of n-butyl vinyl ether. This result suggests that the vinyl ether linkage in the dihydro-pyran ring has no singularity because of its existence in the ring structure.
After the hydrolysis reaction, the resulting solutions of the above two pyran-ring compounds were oxidized with some reagents. In the case of potassium permanganate, periodic acid and hydrogen peroxide, the main product was glutaric acid or glutaraldehyde. On the other hand, nitric acid gave oxalic acid and succinic acid. In this case -hydroxyadipic acid and 5, 6-dihydroxyhexanoic acid (or their lactones), respectively, are considered to be intermediates. The mechanism of oxidation with nitric acid is expected to differ from that with general oxidizing reagents.抄録全体を表示PDF形式でダウンロード (1456K) -

ジャーナル フリーKnown mixtures of fatty alcohol acetates were separated into the saturated, monoenoic, dienoic and trienoic components by the thin-layer chromatography using mercuric acetate adduct method and silver nitrate-silicic acid method.
Sample alcohol acetates were as follows;
1. Steary 1 alcohol acetate.
2. Oleyl alcohol acetate.
3. Linoleyl alcohol acetate.
4. Linolenyl alcohol acetate.
5. Docosenyl alcohol acetate.
6. Sperm whale alcohol acetate.
7. Fin whale alcohol acetates, cow milk alcohol acetates, shark liver alcohol acetates.
Three alcohols of No. 7 were prepared from fin whale oil, cow milk fat and shark liver oil by the reduction method with lithium aluminum hydride.
Petroleum ether : ethyl ether (80 : 20 vol/vol) was better developer than other solvents in the case by silver nitrate-silicic acid method.
n-Propyl alcohol : acetic acid : pyridine (150 : 1 : 1 vol/vol/vol), diisobutyl ketone : acetic acid (40 : 10 vol/vol) were better developers in the case by mercuric acetate adduct method.
Silica gel G was a suitable adsorbent in this experiment.
Monoenoic, dienoic and trienoic fatty alcohols thus showed fine separation on the thin-layer chro-matography.抄録全体を表示PDF形式でダウンロード (517K) -

ジャーナル フリーAcetates of unsaturated primary alcohols were produced when mixtures of unsaturated hydro-carbons and paraformaldehyde were heated in autoclave in the presence of acetic anhydride.
Saponification of these acetates gave the corresponding alcohols.
From α-diisobutylene a mixture of acetate of 3, 5, 5-trimethyl-3-hexene-l-ol and 3-methylene-5, 5 -dimethylhexanol-1, from β-diisobutylene a mixture of acetate of 2, 4, 4-trimethyl-3-oxymethyl-pentene-1 and 3-methylene-5, 5-dimethylhexanol-1 were respectively produced.
Acetic anhydride was more effective solvent than acetic acid in these reactions.抄録全体を表示PDF形式でダウンロード (841K) -

ジャーナル フリーAuthors investigated the reaction of ethylene oxide with aqueous ammonia at high concentration of commercial practice. Kinetically, it is a consecutive and competitive reaction including the follo-wing reactions.
NH3+C2H4O_??_NH2C2H4OH (1)
NH2C2H4OH+C2H4O_??_NH(C2H4OH)2 (2)
NH(C2H4OH)2+C2H4O_??_N(C2H4OH)3 (3)
where k1 = (41+4.0 [H2O]2)×102×exp (-11, 000/RT)
k2 = (7.2-0.042 [H2O])×k1
k3 = (16-0.22[H2O])×k1 in mol-1l min-1.
The reaction rate was maximum when the concentration of ammonia is about 4Owt%
The reactions of ethylene oxide with monoethanolamine and diethanolamine are both accelerated by water, but proceed to an appreciable extent in the absence of water and the rates are proportional to the square root of water concentration. In commercial practice, high temperature and high concentration of aq, ammonia are necessary in parallel, and successive addition of ethylene oxide is recommendable.抄録全体を表示PDF形式でダウンロード (878K) -
