Isobutane, also known as i-butane, 2-methylpropane, or methylpropane, is a chemical compound with molecular formula HC(CH₃)_3.  It is an isomer of butane.  Isobutane is a colorless, odorless gas.  It is the simplest alkane with a tertiary carbon.  A by-product of natural gas processing and petroleum refining, it is commonly used to extract chemicals from cannabis.  Similar to butane and isobutane, propane is one of a group of liquefied petroleum gases (LPG).

With an even lower boiling point, 10.4°F (-12°C), and 1.5 times the vapor pressure of butane, it’s possible that using isobutane as an extraction solvent may pick up even less of the fat and lipids present than using standard butane.  Studies show that the higher the cooling effect, the larger quantity and the higher quality cannabinoids and terpenes can be extracted while leaving even more unwanted byproducts behind.  

In an extraction process, one needs to evaporate the solvent to obtain the desired extract. Isobutane’s even lower, 10.4°F (-12°C), boiling point than butane requires even less heat (burn) to evaporate and makes it even easier to selectively extract trapped residual solvent.  The vacuum turns the isobutane from liquid to a vapor, making it easier to remove.  This allows the operator to extract specific components such as cannabinoids and terpenoids and preserve them at their maximum availability.  The colder the extraction, the lighter the extract, and the fewer the fats and the lipids are left versus other extraction methods.  This property is the key and most important feature in preserving the natural state and the aromatic and chemical complexities of the original plant.  The isobutane solvent can also be converted back to liquid form by either reducing the temperature and/or increasing the pressure.

Using isobutane, low-quality trim, and waste biomass input material can easily be converted into a greater amount of cannabinoid content extract versus other extraction methods. Low-temperature methods with high-quality input material can yield greater quantity, and higher quality crumble.  Isobutane extraction offers the widest array of products that include crumble, shatter, diamonds, sauce, crude, winterized, decarboxylated, distillate, vapes, and formulated products. There is virtually no product that isobutane cannot make, and is a great option for operators that have a diverse product portfolio.
