ジャーナル フリーIn the previous paper of this series, authors reported that a part of peroxides in the original oil changed into polymers during the catalytic hydrogenation. In this paper these polymers were investigated as regards to their structure, mechanisms of formation and also to the effect on oxidative stability of the hydrogenated oils.
In the earlier stage of hydrogenation, the polymers contained compounds with four double bonds in a molecule and trans-trans conjugated double bond, and which were assumed as polymer having a dehydrodimer type structure.
The hydrogenation rate of the dieter was much less than normal glycerides, and even the case of dimer isolated from hydrogenated fat with I.V. 20 it showed I.V. of 75.
Hydrogenated fats contained much dimer had less oxidative stability, and this dimer probably hecomes a precursor of some reverted flavor.抄録全体を表示PDF形式でダウンロード (719K) -

ジャーナル フリーPrins reaction, known as acid catalyzed condensation of formaldehyde with an olefin, gives rather complex mixture of products, mainly composed of 1, 3-dioxanes and tetrahydropyranols, with minor amount of tetrahydrofuran derivatives, unsaturated alcohol and alcohol derived from hydration of the starting olefin.
In this paper authers investigated the Prins reaction of both 1-octene and 2-octene.
The products were isolated by fractional distillation and were purified by gaschromatography.
On the reaction of 1-octene, the major products were found to be 4-hexyl-1, 3-dioxane and both cis- and trans-3-pentyl-tetrahydropyranol-4. The minor products consisted of 3-pentyltetrahydrofuran, 2-octanol and trans-3-nonene-l-ol.
On the other hand, with the reaction of 2-octene, the major products were found to be 4-pentyl -5-methyl-1, 3-dioxane, 4-methyl-5-pentyl-1, 3-dioxane and the stereoisomer of 3-methyl-5-butyl-tetrahydropyranol-4. The minor products consisted of 2-methyl-4-butyltetrahydrofuran, 2-octanol and 2-methyl-3-octene-1-ol.
The conformation of isomeric dioxanes and tetrahydropyranols were determind by NMR.抄録全体を表示PDF形式でダウンロード (1094K) -

ジャーナル フリーA series of cationics derived from chloromethylated 2-ethylhexanol-propylene oxide adducts and various amines were prepared and the surface activities-surface tension, foaming properties, wetting power and emulsifying power-were measured.
The effects of the moles of propylene oxide added and the varieties of amines on the surface activities were studied and the following conclusions were obtained.
1) The cationics derived from propylene oxide adducts and the amine having OH group, especially, show low values on surface tension as compared with the cationics derived from chloromethylated 2-ethylhexanol.
2) On foaming power the cationics derived from the amine having OH group show high values and those having alkyl and phenyl group show low values. The propylene oxide adducts show low values on foaming stability.
3) On wetting power the cationics derived from propylene oxide adducts show good values, especially, for those with amine having OH group.
4) The addition of propylene oxide improves the dispersing power. And the cationics derived from amine having phenyl group show good values regardless to the moles of propylene oxide added.
5) On emulsifying power the cationics having two long alkyl groups are superior, comparatively.抄録全体を表示PDF形式でダウンロード (910K) -

ジャーナル フリーA series of sodium polyoxybutylated octyl, decyl, and lauryl phosphates was prepared by adding 1, 2-butylene oxide to the corresponding alcohols. The relation of their surface activities, such as surface tension, foaming properties, wetting power, dispersing power and emulsifying power, and the length of oxy-butylene chain was studied.
The surface tension of butylene oxide adducts is lower in the low concentration as compared with corresponding alkyl phosphates. Addition of butylene oxide generally improves the foaming power, wetting power, dispersing power and emulsifying power. The foam stability of all products is small.抄録全体を表示PDF形式でダウンロード (739K) -

ジャーナル フリーIt is known that fatty acid methyl ester and triglyceride can be hydrogenated by treatment with hydrazine, but hydrazide is formed inevitably.
In this paper, it was found that soybean fatty acid methyl ester, methyl linoleate and soybean oil could be hydrogenated without the formation of long chain hydrazide by addition of the carboxylic acid such as acetic acid or propionic acid as part of solvent.
The reaction of hydrazine with propionic acid was attempted to clarify why long chain hydrazide does not form in the reactions using carboxylic acid as part of solvent. As a result, the main reaction product was identified as 1, 2-dipropionyl hydrazine.抄録全体を表示PDF形式でダウンロード (352K) -

ジャーナル フリーMass spectra of trimethylsilyl ethers of ethylene glycol, propane-1, 2-diol, butane-2, 3-diol (meso), propane-1, 3-diol, butane-1, 3-diol, butane-1, 4-diol, pentane-1, 5-diol and glycerol were obtained by GC-MS method. The base peak ions of these mass spectra were at m/e 147 in the ethers except those of butane-2, 3-diol and glycerol, which were observed at m/e 117 and 205 respectively. Other features of the spectra were discussed in relation to the molecular weight and structure. GC-MS method was useful for identification of the ethers.抄録全体を表示PDF形式でダウンロード (580K)
