| titleOfInvention | The method for preparing lignin modification furane resins |
| abstract | The lignin modification furane resins prepared the invention discloses a kind of method for preparing lignin modification furane resins and by methods described, wherein methods described of the invention includes：Step (1)：To formaldehyde is added in reactor, regulation pH value is alkalescence, adds lignin, is reacted under agitation；Step (2)：Urea is added to be reacted；Step (3)：Furfuryl alcohol is added, is first reacted in the basic conditions, then adjust the pH value of system for acidity is reacted；Step (4)：Add urea to be reacted, be then dehydrated system under vacuum, then to furfuryl alcohol is added in the system after dehydration, stir to obtain the furane resins of lignin modification.The content of the free furfuryl alcohol of furane resins obtained in the method for the invention and free formaldehyde is low, and can effectively reduce the burst size of formaldehyde during casting mulling, has reached the requirement of environmentally friendly furane resins. |
