PHYSICAL DESCRIPTION
2,2-DIMETHYLPROPANE-1,3-DIOL is a white crystalline solid. Melting point 130°C.
Neopentylglycol (NPG) is a unique polyalcohol offering superior performance advantages in many end-use applications due to its high chemical and thermal stability.
Neopentyl glycol (NPG) is used primarily in base resins for coatings. Important uses are also found in hydraulic fluids, synthetic lubricant oils, greases, metal-working fluids and aircraft engine lubricants. Other outlets include textiles, pharmaceuticals, pesticides, plasticisers and petroleum. NPG is shipped as flake, molten and slurry.
Neopentylglycol (NPG), or 2, 2-dimethyl-1, 3-propanediol,is mainly used as a building block in polyester resins for coatings, unsaturated polyesters, lubricants and plasticizers.
Examples of the various superior characteristics that Neopentylglycol provides to its applications are high hydrolytic stability in polyester resin and high UV stability (UVA/UVB) in powder coating resins.

TECHNOLOGY
There are two main routes to NPG using isobutyraldehyde and formaldehyde. In one, the raw materials react with a strongly alkaline catalyst to form NPG. But, large amounts of formate salts are formed as byproduct and the process is only economically viable when a profitable use is found for the formate.
In a second and more common process, the aldolisation reaction is carried out in the presence of an amine catalyst. This is further hydrogenated in the presence of a catalyst and the molten NPG is solidified by means of a flaking roll, or a crystallising or cooling belt.
Health and safety
NPG is a white, crystalline solid with a mint-like odour. Finely dispersed particles form explosive mixtures in air and it reacts violently with oxidants.
Chemical Properties of Neopentyl Glycol
white solid
Uses of Neopentyl Glycol
NPG Glycol is used in the synthesis of tetraphenylporphyrins. Also used in the synthesis of Bryostatin 2, a protein kinase modulator.

Reactivity Profile of Neopentyl Glycol
2,2-Dimethyl-1,3-propanediol may generate toxic gases in combination of with alkali metals, nitrides, and strong reducing agents. Reacts with inorganic acids and carboxylic acids to form esters plus water. Converted to aldehydes or acids by oxidizing agents. May initiate the polymerization of isocyanates and epoxides.
2,2-Dimethyl-1,3-propanediol readily absorbs moisture on exposure to air.
Used for protection of carbonyl groups as 4,4-dimethyl-1,3-dioxanes, often preferred to the more usual 1,3-dioxolanes due to easier separation and greater stability, for protection of carbonyl group of 4-bromo-2-propanone using p-toluenesulfonic acid in the presence of triethyl orthoformate. It is used in the synthesis of polyesters, paints, lubricants, and plasticizers.
Especially used in paint and coating resin production, gelcoat and powder coating. A very limited amount is converted into esters and used in aircraft engine oil production.
Polyol synthesized by the reaction of isobutyraldehyde with formaldehyde. It is a raw material for polyester resins.

Neopentil Glikolün Reaktivite Profili
2,2-Dimetil-l, 3-propandiol, alkali metaller, nitrürler ve kuvvetli indirgeme maddeleri ile kombinasyon halinde zehirli gazlar üretebilir. Asit ve su oluşturan inorganik asitler ve karboksilik asitlerle reaksiyona girer. Oksitleyici maddeler ile aldehitlere veya asitlere dönüştürülür. İzosiyanatların ve epoksitlerin polimerizasyonunu başlatabilir.
2,2-Dimetil-l, 3-propandiol havaya maruz kaldıkça nemi kolaylıkla emer.
4-bromo-2-karboksilik asidin karbonil grubunun korunması için karbonil gruplarının daha kolay ayrılma ve daha fazla kararlılık nedeniyle genellikle olağan 1,3-dioksolanlara tercih edilen 4,4-dimetil-1,3-dioksanlar olarak korunması için kullanılır. Propanon ile trietil ortoformat varlığında p-toluensulfonik asit kullanılarak hazırlanır. Polyester, boya, yağlayıcı ve plastikleştiricilerin sentezinde kullanılır.
Özellikle boya ve kaplama reçinesi üretimi, jelkot ve toz boyalarda kullanılır. Çok sınırlı bir miktar esterlere dönüştürülür ve uçak motor yağı üretiminde kullanılır.

Reaktivite Profili
2,2-DİMETİLPROPAN-1, 3-DİOL, alkali metaller, nitrürler ve kuvvetli indirgeyici ajanlarla birlikte zehirli gazlar üretebilir. Asit ve su oluşturan inorganik asitler ve karboksilik asitlerle reaksiyona girer. Oksitleyici maddeler ile aldehitlere veya asitlere dönüştürülür. İzosiyanatların ve epoksitlerin polimerizasyonunu başlatabilir.
Neo'nun iki ana hidroksil grubu vardır. Parlak beyaz bir malzemedir. Neo doymuş poliesterlerde toz boya, rulo kaplama ve diğer sızdırmaz emayeler, doymamış polyester jelatin katmanları ve takviyeli plastikler ve sentetik yağlayıcılar için esterler için kullanılır.

TEKNOLOJİ
İzobutiraldehit ve formaldehit kullanarak NPG'ye iki ana yol vardır. Birincisi, hammaddeler NPG oluşturmak için güçlü bir alkalin katalizör ile reaksiyona girer. Ancak, büyük miktarda format tuzu yan ürün olarak oluşur ve bu yöntem, forma yönelik karlı bir kullanım bulunduğunda ekonomik açıdan uygulanabilirdir.
İkinci ve daha yaygın bir işlemde aldolasyon reaksiyonu bir amin katalizörü varlığında gerçekleştirilir. Bu ayrıca, bir katalizör varlığında hidrojene edilir ve erimiş NPG, pullanma silindiri veya bir kristalleştirme veya soğutma bandı vasıtasıyla katılaştırılır.
Sağlık ve güvenlik
NPG, nane benzeri bir kokuya sahip, beyaz, kristalimsi bir katıdır. İnce dağılmış parçacıklar havada patlayıcı karışımlar oluşturur ve oksidanlar ile şiddetli reaksiyon gösterir.
