1. PatentansprAk: 1:o) FOrfaringssatt for framstallning av ett hartsartat forrnbart material genom npphettning av lignin med material innehallande fenol och aldehyd, kannetecknat darav, att ett reaktivt, en alkalisk behandling underkastat lignin, som air-skills i fast form fran en alkalisk losning, upphettas med material innehallande fenol och aldehyd i och for astadkommandet av en kondensationsreaktion. 2:o) Modifikation av sattet enligt patentanspraket 1:o), kannetecknad darav, att det Teaktiva ligninet upploses i en fenol, att en aldehyd tillsattes losningen saint att namnda materialier underkastas betingelser, vilka fororsaka em kondens ation. 3:o) Satt enligt patentanspraket 1:o) eller 2:o), kannetecknat darav, att namnda material upphettas vid narvaro ay en katalysator for att astadkomma kondensationen. 4:o) Satt enligt nagot ay patentanspraken 1:o)-3:o), kanneteeknat darav, att ligninet 4— — erhalles frin avfallslut eller svartlut frin en alkalisk process, sasom soda- eller sulfatprocesscrim. 5:o) Satt enligt nagot av patentansprIken kdametecknat ddrav, att ligninet er- halles frin avfallslut frEn ett surt fdrfarancie. sasom sulfitprocessen, varvid ligninet underkastas en behandling med ett alkali. 6:o) Hartsartat material, frarn stdllt got air forega,encle patenta ospra. Stockholm 1940. Mina Boktr. P. A. Norstedt & Steer 400089Patent claim: 1: o) A process for the preparation of a resinous combustible material by heating lignin with materials containing phenol and aldehyde, characterized in that a reactive, alkaline treatment subjected to lignin, as air-skills in solid form from an alkaline solution, heated with materials containing phenol and aldehyde to effect a condensation reaction. 2: o) Modification of the method according to patent claim 1: o), characterized in that the active lignin is dissolved in a phenol, that an aldehyde is added to the solution so that said materials are subjected to conditions which cause condensation. 3: o) Set according to patent claim 1: o) or 2: o), characterized in that said material is heated in the presence of a catalyst to effect the condensation. 4: o) According to one of the patent claims 1: o) -3: o), it can be deduced from this that the lignin 4— - is obtained from a waste liquor or black liquor from an alkaline process, such as soda or sulphate process cream. 5: o) Set according to some of the patent claims kdametecknat ddrav, that the lignin is obtained from the end of waste from an acidic feed. such as the sulphite process, wherein the lignin is subjected to a treatment with an alkali. 6: o) Resinous material, frarn stdllt got air forega, single patent ospra.
