Što se tiče samog sastava, kanadski balsam, prema Wienhaus-u ima oko 25% terpena (opšte formule .10.1.) a na odgovarajuće smolne kiseline i neutralne delove dolazi oko 75% (opšte formule C20H30O,) (8). Balsam molike ima oko 23% terpentinskog ulja vrlo aromatičnog mirisa a na smolne kiseline dolazi oko 77% (kolofon). Ovo molikovo terpentinsko ulje ima specifičnu težinu od 0,862 a indeks loma mu je 1,462. Literatura: 1. Dri. H. Schmied: Standorte und Bestände für Gewinnung hellen Lärchenbalsams. Ost. Forst,- u.

FIRST TERRITORIAL YIELDS IN THE OUTPUT OF BALSAM OF PINUS PEUCE In the course of 1949, there had been for the first time organized a territorial production of balsam of Pinus peiuce (Grdesebach). The atained results are thus: a) The pitch of 1948 filtered m the course od ´1949 yielded: 38,8% of balsam, 61,2% were apportioned to the remainder of pitch. b) The pitch abtaiimed during the crop in 1949 yielded: 44,8% of balsam and 55,2% of the remaining pitch. The filtration of the remaining pitch yielded: 80,3% of colophony, 12,9% of turpentine oil, 5,8%. of residuens, and 1% of evaporated water. The Pinus pence (balsam) has the specific weight of 0„998 (at a temperature od 2...) its constant coefficient (index) of fracture is 1.316. When filterated it yields 23;% vi turpentine oil and 77% of colophony. The turpentine oil is of a very pleasant and aromatic fragrance. Its specific weight is 0,862, its fracture — coefficinet 1,462. The balsam shows a lioht yellow to a dark yellow colour. The light colour is transparent and of good adhesiveness. 131 |
