1、Designation: D 804 07Standard Terminology Relating toNaval Stores, Including Tall Oil and Related Products1This standard is issued under the fixed designation D 804; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 Although the naval stores industry has been a continuingproducer of chemical products for many centuries, the natureof the
3、 industry, its products, and its terminology have changed.In particular, the original practice of recovering naval storesthrough the processing of the exudate from pine trees (gumnaval stores) has been supplemented by their extraction bysolvent (wood naval stores) and by wood pulping chemicals(sulfa
4、te naval stores). Thus, this terminology contains some oldterms now mostly of historic value, together with the terms ofthe modern naval stores industry.22.

There is no legal requirement underthe Naval Stores Act that the source, origin, or kind of dipentene beshown in the commercial designation. Consequently, coined tradena

The three general classifications or kinds of rosin incommerce are:gum rosin, nobtained from the oleoresin collected from living trees.tall oil rosin, nobtained by the fractional distillation of tall oil.

36、OH.DISCUSSIONIt is generally considered that the term “resin acids” isapplicable to all substances having the specified molecular formulawhereas the term “rosin acids” is only used when referring to thosefound in rosins. They are classified into two groups: the abietic type andthe pimaric type. Both
37、 types and their derivatives are found in wood,gum, and tall oil rosins.rosin adducts, nthe addition product between rosin and ana, b unsaturated carboxylic acid such as fumaric acid,acrylic acid or maleic anhydride.rosin based resins, nresinous products derived from rosin orrosin adducts through ch

39、mation of rosin acid crystalswithin rosin.DISCUSSIONSolid rosin is a supercooled liquid and is normallytransparent. However, when the rosin contains a preponderance of onespecies of resin acid, crystals of that resin acid can form within therosin giving it a hazy appearance. These crystals create ha
40、ndlingproblems as they cause the rosin to become less brittle and moredifficult to break up. Further, the rosin has to be heated well above itssoftening point in order to melt the rosin acid crystals and make therosin homogeneous again. Non-crystallizing rosin also has far bettersolubility in many s
41、olvents and better compatibility with oils andwaxes. The crystallization of rosin can be prevented by changing therosin acid distribution within the rosin through heat treatment with orwithout a catalyst.rosin oil, nthe relatively viscous, oily portion of the con-densate obtained when rosin is subje

43、.rosin standards, nthe combinations of assembled coloredglasses having the colors designated as representative of theestablished U.S. grades used in classifying rosin.DISCUSSIONThe recognized official standards are those developedand issued by the U.S. Department of Agriculture, or similar standards
44、made of Lovibond glass, when certified by the same Governmentagency. The official grades established by or under authority of theFederal Naval Stores Act, for which standards are provided, are asfollows in order of increasing color XC, XB, XA, X, WW, WG, N, M, K,I, H, G, F, E, D, and FF (the latter
45、grade is used only for wood rosin).Rosin darker in color than the standard for Grade D or FF is graded B.The designation Opaque with the grade letters OP is used to describerosin that, because of a turbid, cloudy, or nontransparent condition dueto occluded moisture, excessive crystallization, or pre
46、sence of foreignmatter other than dirt, cannot be accurately graded by comparison withany of the described rosin grade standards. The availability and use ofthese standards is decreasing and being replaced by the use of theGardner color scale.rosin type (sample), na sample of rosin, or a mold ofther
47、mosetting plastic material, used as an unofficial standardin grading rosin.DISCUSSIONSuch sample shall be so selected, sized, and surface-finished that it will have the form of an approximate78-in. (22 mm)cube with at least two opposite faces having smooth parallel surfaces,and shall have a color wh

49、t acidified orotherwise processed, skimmed from the black liquor of thealkaline paper pulp industry, from which tall oil is obtained.softening point of rosin, nthe temperature at which rosinsoftens sufficiently to flow.DISCUSSIONRosin is a glassy-like substance and does not have asharp melting point and so softening point is often used for rosincharacterization. The standard techniques used for measuring thesoftening point of rosin are the Ring and Ball method and the Cup andBall method as described in Test Methods E28a
