5.4.2.4 Application of Nitro Isobutyl Glycerine Trinitrate
Nitro isobutyl glycerine trinitrate is applied in gelatin explosives, which have better
properties than blasting gelatin of nitroglycerine. The explosives have a property of
freezing resistance, suitable for application at low temperature. Except for sensi-
tivity, the other properties are better than ammonium nitrate explosives, whatever
for liquid explosives and powder explosives. Nitro isobutyl glycerine trinitrate also
have wide application potentials in high plastic-type explosives, plastic-type
explosives, dynamite, gelatin explosives (mixture explosives, powder explosives,
gun propellants, and rocket propellants).
By comparison with nitroglycerine, nitro isobutyl glycerine trinitrate has the
following advantages. The freezing point is lower, improving the low-temperature
properties and freezing resistance of propellants and explosives. The sensitivity is
weaker, in favor of the safety in production and application. It has lower vapor
pressure and volatility, less irritating operators. However, there are some disad-
vantages, including poorer stability, smaller speci
c volume than nitroglycerine by
1.5 %, higher detonation temperature than nitroglycerine by 190
9 times
higher viscosity than nitroglycerine. Those disadvantages make nitro isobutyl
glycerine trinitrate often fail in Abel test and be not suitable for propellant powder.

5.4.2.5 Toxicity
Nitro isobutyl glycerine trinitrate is a toxic substance with less toxicity than
nitroglycerine. Its toxicity lies in the irritation to human body. Contacting with
liquid nitro isobutyl glycerine trinitrate, people will have poisoning symptoms of
swollen erythema and headache. However, the symptoms are weaker than that of
nitroglycerine. The prevention and treatment are the same as nitroglycerine.
5.4.3 Property and Preparation of Pentaerythritol Trinitrate
Pentaerythritol trinitrate with the code of ITMETN, also called 1,1,1-trimethylol
ethane trinitrate, trimethylol methane trinitrate, dimethylol-2-propanol-1-trinitrate,
methyl isobutanetriol trinitrate, methyl isobutyl glycerine trinitrate, or methyl tert-
butanetriol trinitrate, is a very important nitrate ester.
5.4.3.1 Chemical Physical Property of Pentaerythritol Trinitrate
Pentaerythritol trinitrate is a light yellow sticky liquid with an odor of burning
alcohols.
