N, N-Dimethylformamide (DMF) was previously found to serve as a good solvent for the carboxylation of alkali phenoxides with carbon dioxide into hydroxybenzoic acids. Thus, in the present study, the carboxylation of phenol in DMF under carbon dioxide pressure in the presence of various metal carbonates was studied. Of the alkali metal carbonates, potassium carbonate was particularly effective.The effects of the amount of potassium carbonate, reaction temperatures, reaction time and the initial pressure of carbon dioxide upon the yield of hydroxybenzoic acids including 4-hydroxyisophthalic acid were studied. The ratio of the p-isomer to the o-isomer formed was then clarified. The stability of p-hydroxybenzoic acid, salicylic acid, and their potassium salts in DMF at high temperatures was also tested. Vigorous evolution of carbon dioxide was noted when they were heated at 280°C and the product consisted predominantly of salicylic acid. Dipotassium salicylate, however, remained unchanged under such conditions.

In order to elucidate the curing reactions of epoxy resins, the reactions between phenyl glycidyl ether and dodecyl mercaptan were investigated. Thus, changes in the number of free epoxy- and mercapto-groups as well as in viscosities were quantitatively determined over a duration of time. The results indicated that the reaction was accelerated by the addition of an amine such as triethylamine and tri-n-butylamine. Ethyl alcohol and metallic sodium, etc. also served as effective catalysts. Addition reaction of dodecyl mercaptan to phenyl glycidyl ether occurred at temperaturesand above 40°C in the presence of a catalyst such as triethylamine . above 150°C without catalysts. jn the presence of triethylamine phenyl glycidyl ethev reacted more readily with lauryl alcohol than dodecyl mercaptan .

The kinetics of the Friedel-Crafts reaction of chlorobenzene with each one of cyanuric chloride and 2, 4-dichloro-6-methoxy-s-triazine (DCMT) were investigated. In all cases, large excess of chlorobenzene was used, and theprogressof reaction was followed by measuring the hydrogen chloride formed. Three chlorines of cyanuric crhloride were thus reacted with chlorobenzene by consecutive reactions, and the apparent velocity constants k₁ 's at 100, 110, and 120°C in the first step were found to be 1.34 × 10^-3, 1.89 × 10^-3, and 2.18 × 10^-3 (min^-1), respectively. The relative ratio of rate constants in the three steps was approximately k₁ : k₂ : k₃=3 : 2 : 1. In the reaction of chlorobenzene with DCMT, it was found that the yield of the condensed products increased with an increasing amount of anhydrous aluminum chloride used, and one mole of anhydrous aluminum chloride consumed for the demethylation of DCMT.

It has been found that 2-amino-4, 6-disubstituted-s-triaziies are readily obtained from imidoylguanidines upon treatment with an acid chloride or an ester in a good yield even at low temperatures. This method is also applicable for the preparation of oligomers containing s-triazine rings. Some of their properties are reported.

Reactions between 3, 7-dimethyl-1, 6-octadiene (2) (dihydromyrcene, citronellene or 2, 6-dimethyl-2, 7-octadiene) and t-butyl perbenzoate were studied. Thus (2) was treated with t-butyl perbenzoate at 86-120°C in the presence of cuprous salts, and the product saponified to obtain a monoterpenic alcohol fraction in 24-45% yields. By vapor phase chromatography and IR spectroscopic analysis, the monotrepenic alcohol fraction proved to consist mainly of three components; 3, 7-dimethyl-1, 5-octadien-7-ol, linalool and 3, 7-dimethyl-1, 7-octadien-6-ol, in an approximate ratio of 1 : 1: 2.5.
