中文名:脂松香,英文名:gum rosin,CAS:8050-09-7,化学式:C19H29COOH,分子量:302.451,密度:1,07 g/cm3,熔点:70-72°C,沸点:439.5°C at 760 mmHg,闪点:180°C,水溶性:Soluble in alcohol, benzene, ether.

Gum rosin is an organic compound of monoterpene, turpentine and resin acid. Also known as colophony or rosin, it is a solid form of pine oleoresin from pine trees (mostly conifers). It is produced by heating fresh liquid resin in order to vaporize the volatile liquid terpene components.

松香的主要成分为由分子式为C20H3002的树脂酸组成的化合物，该类树脂酸为具有三环菲骨架的含有两个双键的一元羧酸，松香的双键为共轭双键，化学活性强，因而通常需要对其进行加氢、歧化反应等处理以生成稳定化的松香。 其中，相对于氢化松香，歧化松香由于生产成本较低因而市场的用量比较大。 松香主要从松树的分泌物中提炼而来, 是自然界极其丰富的一种天然树脂, 也是一种可再生资源。松香的组分随原料产地和加工方法不同而略有差异, 主要是由树脂酸和少量中性 …

Glycerol ester of wood rosin (or gum rosin), also known as glyceryl abietate or ester gum, is an oil-soluble food additive (E number E445). The food-grade material is used in foods, beverages, and cosmetics to keep oils in suspension in water, [2] and its name may be shortened in the ingredient list as glycerol ester of rosin. It is also used ...

2023年7月20日 · Gum rosin, also known as colophony, is a natural resinous substance derived from the resin of pine trees through a process called tapping. Indonesia stands as a major producer of gum rosin, and its unique properties make …

Gum rosin is categorized into various grades determined by its color and softening point. The softening point is the temperature at which rosin begins to deform under pressure. Generally, the darker the rosin, the lower its softening point. The table below showcases some rosin grades and their corresponding properties.

Gum Rosin, also known as colophony, is a natural resin derived from pine trees. It has been used for centuries in various applications due to its unique chemical properties and versatility. Gum Rosin is obtained through a process of tapping pine trees, collecting the resin, and then processing it into solid, translucent lumps or in powdered form.
