| 摘要 |
Hydroxymethyl-dialkyl-phenols are prepared by reacting the appropriate dialkyl phenol with formaldehyde in alkaline solution. Specified hydroxymethyl phenols are 2-hydroxymethyl, -3,5- or 3,6-, or 4,5- or 5,6-dimethyl phenol, 2 - hydroxymethyl - 3 - methyl - 5- or 6 - isopropyl phenol and 4-hydroxymethyl-2- or 3-methyl - 5 - isopropyl phenol. Increasing the quantity of formaldehyde gives phenols with two hydroxymethyl groups, e.g. 2,4-dihydroxymethyl - 3 - methyl - 6 - isopropyl phenol. Specification 941,803 is referred to. |
