Aldehydes in $\gamma$-irradiated Solid Starch

A study of the radiation-induced formation of carbonyl compounds in solid starch by means of precipitation with 2, 4-dinitrophenylhydrazine and subsequent analysis of the hydrazones by gas chromatograph has been performed. formation of carbonyl groups was found to increase linearly with increasing doses up to about 2$\times$10$^{21}$ eV/g. Generally, at least 5 different peaks can be detected including formaldehyde and acetaldehyde.

고체전분이 방사선에 조사될때 생성되는 carbonyl 물질이 gas chromatograph에 의하여 검파되었는데 2,4-dinitrophenylhydrazine으로 침전시켜 얻은 hydrazones을 분석하였다. Carbonyl groups의 생성은 선량이 2$\times$$10^{21}$ eV/g될때까지 직선으로 증가하며 form-aldehyde와 acetaldehyde가 검파되었다. 이외에 최소한 미상의 3개의 peak가 발견되었다.
